Do-it-yourself spark plug tuning

Why do you need to modify spark plugs?

Let's start with the fact that owners of old gasoline cars, mainly carburetor ones, should modify new spark plugs for good economy and increased power.
As a rule, it is on such a dosing system that the issue of gasoline consumption is most acute. In parallel with this, modifications can have a positive effect on the injector. At the same time, high-tech modern spark plugs with an extended service life (platinum, iridium) should not be modified. It turns out that changes and modifications are most relevant only in relation to ordinary candles. Now let's take a look at the practical benefits of upgrading candles.

First of all, ease of starting and, as a result, less risk of flooding the spark plugs. This is especially true in winter, when fuel evaporates less easily in a cold engine, the battery charge naturally drops, the oil becomes sticky and the starter turns the engine weaker.
Another advantage that “tuning” spark plugs promises is stable operation of the internal combustion engine in different modes, (especially at maximum loads and high speeds), even taking into account that the composition of the fuel-air mixture will not be optimal, that is, the working mixture is too lean or enriched.
Note that under conditions of high pressure on modified spark plugs, less impact is exerted on the spark, which is simply blown away on a standard spark plug. As a result, the power unit not only starts well, but also burns the fuel charge more fully, delivering more power. This reduces fuel consumption and results in savings.

What's the result?

As practice shows, after tuning the spark plugs, engine power, on average, increases by 5-6 hp. These figures were obtained by car owners after testing on a dynamometer. At the same time, the torque increases. Taking into account the simplicity and accessibility of the method, such an increase can be considered quite significant.

We also note that many motorists actively practice this solution. There have been cases where a set of the simplest old spark plugs with a mileage of about 25 thousand km. on bad fuel, after unscrewing from the engine, they were thoroughly cleaned, and then modified using the method described above. After modernization, these spark plugs continued to work normally for at least another 10 thousand km.

We also recommend reading the article on how to select spark plugs based on the make and model of your car. From this article you will learn about the features and criteria for the correct selection of spark plugs for a specific engine.

Finally, we would like to add that some drivers are skeptical about modernization. The main argument is that candle manufacturers themselves cannot but know about such a simple method of improvement, but still do not introduce it into mass production for some reason. Please note that we will not try to refute this statement.

Perhaps laboratory tests in factory conditions reveal something that ordinary car enthusiasts do not know. As for possible harm to the engine, practical operation on CIS roads did not reveal any noticeable problems with engines after driving with modified spark plugs.

At the same time, for owners of old cars, it is more important to change spark plugs as rarely as possible, while simultaneously achieving fuel savings, than to monitor a worn-out internal combustion engine with the utmost attention.

Why and when do you need to replace spark plugs?

Spark plug heat number

Spark plugs in a car are responsible for creating a spark, thereby igniting the fuel mixture in the cylinder. The power and starting of the engine and fuel consumption depend on their condition and serviceability. That is why it is necessary to know after what period it is necessary to replace spark plugs with your own hands, as well as how to do it.

The service life of spark plugs is given in the vehicle operating instructions. They are replaced as they wear out, and usually this is 50-60 thousand km. But in reality everything turns out a little differently. The service life of spark plugs also depends on the quality of the fuel supplied, the health of the engine, regular maintenance and many other factors.

The quality of the fuel greatly affects the life of the spark plugs. Therefore, in our reality, spark plugs are replaced at intervals of 25-30 thousand km.

Spark plugs are an important part of any gasoline engine, however, like any other part, they are also subject to wear.

Poor engine starting.
Increased fuel consumption.
Reduced engine power.
Unstable engine operation.

However, it is worth remembering that the above malfunctions can indicate not only a problem in the spark plugs, but also about breakdowns in other systems. To do this, you need to remove them and inspect them. Let's look at how to replace spark plugs with your own hands.

For this procedure, you will need a special spark plug wrench, a torque wrench, an extension socket, a ratchet, and a socket the size of your spark plug.

Before you begin removing the spark plugs, remove any sand or dirt that may have accumulated around them. It is done quite simply, using a regular brush. A compressor is also great for these purposes. Clean spark plug wells thoroughly.

Why did the question arise about how to improve spark plugs with your own hands?

Spark plugs
There are more and more people who are ready to buy a car at an affordable price, and then tune it and modernize it. And this category of people is themselves creative, capable of experimenting, taking decisive steps, and even seriously thinking about how to improve spark plugs with their own hands.

Tuning

Perhaps a used foreign car will not give in in some way, will not allow itself to be remade, but, as they say, nothing is impossible. The structure of domestic machines is more open, and it opens up a wide field for the activity of the imagination. So there are those craftsmen who think about how to improve spark plugs with their own hands. What motivates automobile “Kulibins”, what do they want to achieve?

Experienced experimenters claim that they know exactly how to improve spark plugs with their own hands. When they managed to perform this procedure, that is, bleed the spark plug, they achieved the desired results:

The spark is not blown away by the resulting pressure
All possible engine performance increases almost before our eyes
Gasoline burns completely, so less fuel is consumed.
The machine control system is working properly.

Another reason why some people want to improve the performance of a candle. After all, many people know that its service life is short, lasting an average mileage of 15,000 km, and then you need to monitor its condition, assess whether carbon deposits appear on it, or whether the housing or electrode may even be damaged.

All words of indignation addressed to the candle appear at the moment when visible problems with the car manifest themselves, the vehicle jerks or loses its power. And who will like it! That’s why there are brave souls who are able to radically decide how to improve spark plugs with their own hands and no longer think about gasoline consumption or loss of power of a reliable car. Opponents may remind you that although the candle will be improved, its lifespan cannot be extended. And in general, who will guarantee that the calculations were chosen correctly, that the innovative work being carried out will not turn into disaster and further costs for repairing the vehicle and its expensive components.

Spark plug

Selection of Denso iridium spark plugs by car

A spark plug is a device for igniting the fuel-air mixture in a wide variety of heat engines. There are spark, arc, incandescent, catalytic, semiconductor surface discharge, plasma igniters, etc.

Gasoline internal combustion engines use spark plugs. The fuel-air mixture is ignited by an electrical discharge with a voltage of several thousand or tens of thousands of volts that occurs between the electrodes of the spark plug. The spark plug fires every cycle, at a certain point in engine operation.

In rocket engines, the spark plug ignites the fuel mixture with an electrical discharge only at the moment of launch. Most often, during operation the candle is destroyed and is not suitable for reuse.

In gas turbine engines, the spark plug ignites the stream of fuel emerging from the fuel injector at startup with a series of powerful arc discharges. After this, the combustion of the fuel torch is maintained independently. As a rule, surface discharge spark plugs are used, powered by high-frequency high-voltage current from the ignition unit. There are most often two spark plugs (for reliability), each installed in an igniter with a special starting nozzle that works only when starting, which protects the spark plug from burning when the engine is running.

Glow and at the same time catalytic spark plugs are used in model internal combustion engines. The fuel mixture of engines specifically contains components that are easily ignited at the beginning of operation from the hot spark plug wire. Subsequently, the filament heat is maintained by the catalytic oxidation of alcohol vapor included in the mixture.

Story

The first spark plug in its modern form was developed by the German engineer and scientist Robert Bosch in 1902. For the first time, the spark plug was used with a high voltage magneto, also developed in the BOSCH workshop. BOSCH spark plugs began to be used in Karl Benz's internal combustion engines, replacing the open-flame glow tubes used at that time. From then to the present, almost all spark plugs use the same principle of operation and structure as in 1902; the evolution of this unit has been mainly along the path of improving the materials used (for insulators, conductors, etc.) and manufacturing technology ( cheaper).

Spark plug device

The spark plug consists of a metal body, an insulator and a center conductor. Modern spark plugs may have a built-in resistor between the contact terminal and the central electrode.

Contact pin

The contact terminal located at the top of the spark plug is designed to connect the spark plug to the high-voltage wires of the ignition system or directly to an individual high-voltage ignition coil. Several slightly different designs may occur. Most often the wire to the spark plug has a snap contact that

What can be made from old spark plugs

Experienced motorists know that the engine in any car, like a person’s heart, gets so tired with age that sometimes it not only works poorly, but even stalls and then doesn’t want to start.
Therefore, he needs “treatment” more and more often. Moreover, replacing rings, pistons and valves does not always improve the efficiency of the internal combustion engine.

The ignition system and, first of all, the spark plugs also play a big role in this.

For a car with “experience”, the issue of starting the engine is very relevant, especially in areas with harsh climatic conditions. As you know, the size and shape of the spark discharge is of great importance.

The spark parameters are especially important when the engine is running cold, when the fuel mixture entering the combustion chamber is far from a gaseous state.

To improve the quality performance of the spark plug, a very simple modification is proposed, which can be done not only by a home craftsman, but also by any car enthusiast who knows how to hold a hammer and pliers.

It should also be noted that the proposed modification will be useful not only for carburetor internal combustion engines. It will help improve the performance of injection systems and even turbocharged engines. Reducing the effect of blowing off the spark discharge will improve the ignition of gasoline and the completeness of combustion, which will immediately affect the engine response and the stability of its operation, especially at high speeds.

A conventional spark plug consists of 2 electrodes separated by a powerful ceramic insulator.

The central electrode is a steel rod, one end of which has a thread for a contact nut, the second is a smooth cylinder located in the discharge zone.

The other electrode is connected to the spark plug body and, in the form of a rectangular rod with the letter G, is brought into the sparking zone, located through the air gap directly above the first.

The effective volume of ignition of the mixture is also “sandwiched” by the electrodes.

The proposed modification, “seen” in the multi-electrode designs of spark plugs for sports cars, will not only release the discharge, but also increase its length, and, therefore, the effective volume of fuel in the spark zone of the cylinder.

Small manipulations with the spark plugs will help you make sure that your engine is far from old and can easily run both in the summer heat and in the twenty-degree frost in the harsh winter.

Oddly enough, the service life of such spark plugs increases somewhat as a result of modifications.

Now let's move from theory to practice and consider the manipulations that need to be performed on a standard single-electrode spark plug, both imported and domestic, in order to implement what is described above. So, let's do everything step by step:

for safety reasons, turn off the ground or disconnect the positive terminal of the car from the battery;
disconnect the high-voltage wires and twist the spark plugs that need to be modified;
measure the required length of the side electrode and use a marker or a file to mark the section to be cut off;
we clamp the metal body of the candle in the yew jaws with a force that allows us to ensure its reliable fixation without any damage;
using a hacksaw or cutting disc of an angle grinder, carefully cut off the excess part of the electrode;
carefully process the cut site with a fine file, ensuring an even, straight cut without burrs;
Using round pliers we bend the electrode so that its edge is at the same height as the central electrode, and the air gap corresponds to the passport value;
repeat the above operations on each spark plug;
we screw in the spark plugs and put the caps of high-voltage wires on them;
turn on the ground, ignition and start the engine.

As a result of the “surgery” performed on the spark plugs, as expected, we significantly increased the length of the spark discharge. Now the spark “breaks through” from the side gap to the very center; it has the shape of an arc, facing directly into the fuel combustion chamber, and covers a much larger volume of space.

It is precisely this “trick” that allows the fuel mixture entering the cylinders of the internal combustion engine to ignite better and burn more completely.

In order not to be unfounded, we will say that diagnostic tests of the carburetor engine of a VAZ car on a stand after modification of the spark plugs showed an increase in its initial power within an additional 6-7 horsepower.

In conclusion of this article, we can advise you the following. If you don't trust us or are not entirely confident in your abilities, don't worry too much.

You can perform all the operations described on old spark plugs, probably stored in the glove compartment “in reserve.”

The most important thing is that the elements being upgraded are “live” (without shorting the electrodes across the insulator), otherwise you will not succeed.

Good luck!

HomeCar TipsWhat can be made from old spark plugs

Such a question as modifying spark plugs with your own hands may be relevant for those who have a fairly old gasoline car. The information is quite interesting. Let's see how such improvements are useful in practice? Firstly, even despite the severity of climatic and other conditions, the engine always starts very easily, without any nuances.

Even when the mixture of fuel and air is not entirely optimal, the engine is stable at high speeds. When supercharged at high pressure, the possibility of blowing out the spark plug (when the spark is blown away) is reduced. The performance of the engine and its response to your actions improve, and gasoline burns quickly and much more completely.

Hence, the efficiency of work increases and the consumption of fuel mass decreases. Do-it-yourself modification of spark plugs can be done according to the type of sports series products produced by some companies that develop spare parts. Such spark plugs significantly increase power and reduce consumption, and manufacturers provide guarantees of almost 100 thousand kilometers without any significant loss of quality functioning.

But in practice everything looks much more modest. The efficiency of these structures, despite their high cost, noticeably decreases after only 10 thousand km, and throwing them away and buying new ones is quite expensive. What can be done in such cases to preserve the candles longer and increase their intended effectiveness?

In order for the spark plug to become effective again, we need to use a simple tool to make the electrode on the side shorter, and then start adjusting the gap. Moreover, the shortening must be done so that the central electrode does not overlap with the side one;
We unscrew the candle on which you plan to perform these actions from its location (or, as an option, take a new one);
Using a glass marker, mark on the desired candle the length to which the side electrode needs to be cut.
We fix the spark plug in a small vice (the main thing is not to overtighten);
Take a grinder (Dremel or any other company) with a cutting disc installed. Carefully shorten the electrode, which is located on the side. The result should be a smooth, parallel cut, not slanting to the sides;
We clean the place of the cut with a file to remove burrs and irregularities;
Next, set the specified gap. It is different on different brands of cars and trucks, domestic and foreign, turbocharged and not. So, in this case, it is better to navigate through a book or look on the Internet;
A similar procedure must be performed with each candle separately. Then we screw them into place and try to start. I think you should like the effect produced.

What do we have as a result? After the execution, the spark front will increase, and significantly. After all, now the flame is directed directly into the combustion chamber of the fuel mixture. Whereas in a candle, according to standards, the fire is, as it were, sandwiched between the electrodes, side and central. This simple, universal improvement allows the flame to spread more freely, resulting in faster, more complete combustion of gasoline and increased engine power.

Interestingly, when measured on a dyno, for example, judging by the graphs, the increase was 7 additional horses! And this, you see, is not so little. The torque has also been increased slightly. Plus - the same fuel economy and other pleasant nuances, for which, probably, the whole business was worth starting. Checks and doubts You can check the operation of the modernized spark plugs by building a simple stand in the garage from a distributor, a coil and a battery.

It will be immediately visible to the naked eye that the spark produced by the spark plug has improved and intensified. Thus, in fact, the old candle will continue to work efficiently for quite a long time. The only thing that raises some suspicions is: why do some manufacturers continue to produce products that are not finished using this method?

What resistance should be on the spark plugs, how to make a tester for SZ with your own hands

Hot: the insulator area is much larger than that of a cold one, so it is heated by gases in the combustion chamber. The transition zone to the outer shell is minimal;
Cold: they have an elongated area for heat removal; accordingly, the working surface heats up much less.

A combustible mixture in the form of gasoline and air enters the combustion chamber in the ratio through the passage channels of the valves;
The valves opened due to the rotation of the starter;
The spark plug supplies a spark that was supplied by the ignition coil through high-voltage wires;
At this second, a micro explosion occurs in each cylinder in turn, which sets the engine in motion.

I tore off the thread for the candle and what should I do now?

That's what, but I never thought about this, and no one warned me - that you can break the thread for a candle. But one day this happened to me, and I realized that the situation was practically unsolvable. Well, I was faced with two problems: how to get to the service center and how to actually fix it.

Warm summer day. We gathered with our comrades in a garage cooperative to trick our swallows. One of them had a compression gauge with him and we set out to measure the compression of my car. They measured the compression and I started screwing the spark plugs back in. Three of the most awkward twists (I try to twist everything from the most difficult to the simplest).

When I removed the key (a special head with a rubber dome), take this very dome, but it gets caught on a spark plug and falls under the car. I was too lazy to get it out and I decided to screw in the last candle without this dome - what a fool! I started to tighten it, it seemed to go on easily, only the candle had a worn thread and was stuck at an angle, since there was no holding dome. As a result, the candle went on, but it was kind of tight. I thought it was time to put on the ratchet and call it a day. And the circus began.

I twist the candle, but she doesn’t even think about resisting. I'm trying to unscrew it - it's too easy. Well, that’s the end, I thought, and I was absolutely right. I took out the spark plug and saw that there were remnants of threads from the cylinder head on it. Moreover, these remains represented 80 percent of what used to be carvings. The thread on the candle was almost undamaged. The cooperative is located on the other side of the city and I need to somehow drag the car at least to the parking lot. First we tried sealing the threads with foil, but it didn't work. Then I found a spark plug with an excellent high thread in my trunk and we screwed it in. Without fanaticism and tension.

Let me back up a little - you can’t do this. Half a year later, a candle with a worn thread shot out in exactly this way. It turned out like a bullet that had not completely passed through the hood, that is, a dent and a small hole - it’s good that it hasn’t hit anyone in the eye yet.

As a result, I went home with a candle “on the snot”. I tried to turn the engine as low as possible so as not to shoot. I'm lucky. I drove home like this, and then to the service center.

Repairing threads in a spark plug well

I myself did not take on this work, because the cost of a mistake is quite high, but at least you can ask the service for something. Repairing threads in the cylinder head is as follows:

A special thread tap is inserted into the well, 2mm larger than the former thread
The tap is generously lubricated with grease so that all the resulting chips do not fly into the combustion chamber (this metal will not burn and is guaranteed to cause scuffing on the cylinder walls if it gets into the space between the piston and the cylinder wall), but remains on the grease.
a new one, but of a larger size, is stamped on top of the old thread
Further options are possible: either a spiral or a barrel, called a futor, is screwed in
Both sit on a special thread locker

This repair cost me 1200 rubles. On the downside, the barrel constantly tried to get out of the way, but when I overhauled the motor, this issue was resolved by flattening the barrel on the reverse side.

Not all motors can be repaired, and even on one motor you can access part of the spark plug wells with a tap, but not part of it. I was also lucky in that if I had torn off the threads not on the first, but on the second cylinder, I would not have been able to repair the threads without removing the head.

Well, the method of repairing threads by removing the block head is applicable in most cases. However, it is worth remembering that when removing the head, it is necessary to change the cylinder head bolts and cylinder head gasket.

In general, be careful when unscrewing and tightening spark plugs. Don’t forget to read my article on this topic about the intricacies of replacing spark plugs.

Signs of faulty spark plugs. List

1. The starter turns for a very long time, but the engine does not start or starts, but after a long time;
2. Unpleasant noise made by the engine when the car warms up or during idling;
3. Increased gasoline consumption during vehicle operation;
4. The number of harmful substances from the exhaust pipe has increased;
5. Spark plugs are wet or filled with fuel;
6. Weakening of the car’s traction, lack of power and failure to gain the required speed.

1. Open the hood and secure it with a stand;
2. Blow compressed air through the engine to clear it of road dust. To do this, you can use a regular home vacuum cleaner, only by turning it on to “exhale” air, and not to suck it in;
3. Remove high-voltage wires or ignition coils, depending on the type of engine, to get to the spark plug wells;
4. Using a spark plug wrench, unscrew all the spark plugs and remove them using wires or a special head;
5. Check for the presence of oil and foreign objects in the wells using a flashlight, so as not to provoke rapid failure of new spark plugs;
6. Insert and tighten new spark plugs, connect the high-voltage wires and you can start the car engine;
7. After starting the engine, check for detonation, which may occur due to the installation of low-quality spark plugs.

Do-it-yourself modification of spark plugs

The modernization is based on the task of bringing simple spark plugs closer in a number of parameters to the so-called sports spark plugs. Such products are offered by many well-known manufacturers, but they are significantly more expensive.

Sports spark plugs allow you to increase power and reduce consumption; the declared service life of such elements is 70-90 thousand km. mileage However, in practice, the efficiency of their work decreases, on average, after 15 thousand km, and such spark plugs do not last the entire stated period. Taking into account the high cost, buy these elements every 30-35 thousand km. it turns out to be expensive.

It is for this reason that many drivers do not strive to immediately change a set of spark plugs, since there are ways to extend the life of existing ones. The best way to solve the problem is to modify conventional or sports spark plugs.

The procedure is not complicated, so even beginners can handle it:

to make the spark plug work as efficiently as possible, you will need to shorten the side electrode;
the next step is to correctly adjust the gap on the spark plug;

Now let's take a closer look. Regarding the first point, shortening must be done in such a way that the central electrode is not blocked by the side electrode.

The whole process looks like this:

Used spark plugs are unscrewed from the engine or prepared in advance (you can work with new elements); Next, using a marker or another method (for example, a notch is made), a special mark is applied to the side electrode, which will indicate to what length the electrode should then be shortened. Next, the spark plug is carefully clamped in a vice (preferably with rubber “lips.”) It is important not to overtighten the vice so as not to damage the element. After this, you will need to take a grinding machine and install a cutting disc; Use a tool to shorten the side electrode. In this case, it is important to ensure that the cut is smooth, without bevel. Then the cut site is cleaned with a needle file, nicks are removed, edges are leveled, burrs and other defects are removed. Now you can start setting the desired gap

The value will depend on the type and model of the internal combustion engine. In this case, it is best to use the manual, get the necessary information on specialized automotive forums, etc. Shortening the electrode and setting the gap on the spark plugs must be done with each spark plug, and be sure to maintain the highest possible accuracy (how much is cut off from the electrode and what gap is set). After installing the modified spark plugs on the engine, it is necessary to perform a test run. As a rule, starting should be easier than with conventional spark plugs. Then you can take a trip, appreciating the stability of operation and improved throttle response of the internal combustion engine, as well as better traction at high speeds.

You can also visually evaluate the performance of the candles. To do this, it will be enough to make a test stand right in the garage. For manufacturing you need to have a distributor, a coil and a power source.

Next, the usual spark test is performed, which will demonstrate an increase in spark formation, a change in the color of the spark to a bright blue-red, etc. It is optimal to carry out the check in the form of a comparative analysis, that is, compare the spark, its power and color before starting work (on standard spark plugs) and after (on modernized spark plugs).

If we talk about the modification itself, the simple manipulations described above make it possible to expand and significantly increase the front of the electric spark. In other words, the spark, after removing part of the electrode, is not sandwiched between two electrodes (side and central), but is immediately directed into the combustion chamber.

As a result, the ignition efficiency of the fuel and air mixture in the engine cylinders improves, and subsequent charge combustion becomes more complete. The dependence of ignition on the quality and intensity of spark formation on the spark plug in relation to the composition of the working mixture is also reduced.

In other words, a more powerful spark more easily ignites a rich or lean mixture to varying degrees, which has a positive effect on the overall performance of the engine under load and in other modes. If the mixture is better ignited by a spark, then the flame front spreads more evenly and freely, gasoline burns fully in the cylinders, power increases, and fuel consumption decreases.

How to improve spark plugs with your own hands

The question among creative car enthusiasts about how to improve spark plugs with their own hands is becoming more and more urgent; opponents echo them in response: “Does anything need to be changed in a well-coordinated car control system?” Let’s try to figure out which one is right one by one.

Finally, the era has begun when a vehicle is not an excessive luxury, but a means of transportation.

Brands of cars from domestic manufacturers are already available at affordable prices, and a secondary car market system has been established, where it is very easy to buy a car second-hand and exchange it for a more budget model.

It seems that there are no longer any restrictions and conventions for a person who wants to buy a car. There is a vehicle to suit every pocket.

Innovators want to increase the power of the vehicle, thinking that by changing the degree of caviar supply, they will increase the performance of the power unit. An impressive argument for drivers who cannot live without high speeds.
But opponents of the idea of improving spark plugs remind that any design features of a vehicle are driven into its limiting capabilities. And if you only influence the degree of spark supply and don’t change anything else, then whether progress in implementing the idea is possible or not is still a big question.
You need to solve the question of how to improve spark plugs with your own hands with a cool head and nerves of steel, as well as with a large amount of knowledge and experience in conducting experiments.

Using a simple marker, mark on the electrode the location of the desired cut off of the part.
Clamps the candle in a vice and continues to adjust the shape of the product.
Using a grinding machine, we cut off the unnecessary segment that was previously marked.
We clean the cut-off area with a file suitable for cutting. The goal is to remove unevenness and roughness, and chips.
We adjust the gap required according to the diagram. The distance depends on the make of the machine and the expected load on it.
All that remains is to return the upgraded spark plug to the standard seat. And start the car, evaluating the result obtained and realizing whether you managed to professionally solve the problem of how to improve spark plugs with your own hands.

After cutting off part of the electrode, the spark front will increase, so the flame will go straight into the combustion chamber. As a result, we should expect complete combustion of gasoline, a small but increase in vehicle power.

The second way to improve spark plugs with your own hands is to carefully bend the electrode, simply forcibly increasing the distance between the components of the spark plug. Many people resort to this method, but due to lack of skill, the spark plug can be damaged. And remember that you cannot remove a faulty spark plug from the system; it will be very difficult to foresee the consequences. Bend back the electrode

Thus, you can determine several answers to the question of how to improve your own spark plugs, and they will be polar. Firstly, if changes are introduced into the system, the calculations must be verified. Secondly, you should not push the car beyond its capabilities, because by increasing its power by force, you can actually reduce its service life.

We would like to know how many car enthusiasts are in favor of improving the spark plug, and who definitely says “no” to such an idea. State your position in the comments, we will be grateful for it.
