Replacing spark plugs for Lada Vesta. Advice from experts, reviews, service life

What kind of spark plugs are installed on Lada Vesta from the factory?

The type of igniters differs in size, depending on the number of valves. In an 8-valve engine the skirt is short, in a 16-valve engine it is long. The standard configuration is from a domestic manufacturer, but nothing prevents the owner from installing imported analogues.

Which spark plugs to choose for Lada Vesta: factory opinion

AvtoVAZ specialists recommend the manufacturer NGK BCPR6ES for both 8-valve and 16-valve engines.

Note to the driver! When replacing spark plugs 16-cl. motor, use a hex wrench set to “14” (it is smaller than for 8-kl).

↑ Replacement period

For a car, as for any other equipment, it is better to prevent the breakdown of any small spare parts with the help of timely maintenance than to experience difficulties with repairs in the future. Therefore, even when purchasing a completely new car, the owner is given a number of recommendations for operating the car and the necessary periodic maintenance.

AvtoVAZ, among other things, sets timing for replacing spark plugs for cars of the entire model range, including the new Lada Vesta. Plant specialists recommend changing them after every 30,000 kilometers. In fact, the resource of their candles, and any others that will be installed, is approximately twice as long. But due to bad gasoline and polluted air, it is possible that the igniters will fail the car owner at the most inopportune moment if they are not replaced within the specified period.

Features and purpose of spark plugs

Without the spark produced by the igniter, the engine will not start and the combustible mixture will not ignite.

The average life of an original spark plug is 40,000 km or three years, whichever comes first.

The following models are distinguished: conventional, iridium, one-, two-, three-, four-electrode. Iridium ones are 10–15% more expensive than all other types.

The greater the number of electrodes, the greater the likelihood of rapid combustion of the mixture. For domestic cars this is not so important: one electrode is enough.

Standard reel - article number and price

Let's look at the articles, the cost of the IKZ, you can navigate by price. Lately, counterfeit parts have become common. By buying such a fake, you reduce its use by half. In order for the car to work well, the choice of parts should be approached with full responsibility.

• 2112-3705010-12 JSC "SOATE", Stary Oskol - 1165 rubles.
• IKZ – 1000 rub.
• 2112-3705010-11 “ITELMA”, Moscow – 1215 rubles.
• 2112-3705010-13 “NORTH”, Novosibirsk – 1515 rubles.

As you can see, ignition coils are affordable and you can purchase them without significant damage to your wallet. How to distinguish a fake from a factory IKZ:

1. The first distinguishing feature is that the original reel has a body made of plastic, while the fake one is made of metal.
2. The fake part lacks special stamps and a lightning bolt symbol, which indicates high voltage. If you look closely at the contacts of a fake IKZ, you will notice that they are thicker and round. The factory number is marked with an oval on the original part.

What is the difference between spark plugs for 8- and 16-valve engines?

By and large, there are no differences, except for the size of the key that needs to be used to unscrew the case.

Regulations for replacing spark plugs on Lada Vesta

16 valves under the hood of Vesta.

When the critical time has come, the first question is what elements are best to use so that it lasts longer and the work is more or less satisfactory. In order to ignite the combustible mixture of atmospheric engines, an electrical discharge of tens of thousands of volts is required. For this we need decent specimens.

According to recommendations, spark plugs need to be changed every 30 thousand mileage.

In fact, it turns out that the potential of the spare part is much greater, presumably by another 100%. Problems with the quality of fuels and lubricants and other nuances prevent the operation of mechanisms under conditions close to ideal. For this reason, 30 thousand is a good number that should not be neglected.

Lada Vesta can be equipped with one of two engines: VAZ-21129 and VAZ-21179 with working volumes of 1.6 and 1.8 liters (power 106 hp and 122 hp, respectively). But the candles that go with them are the same, so there is no fundamental difference. During the preparation of the car for routine maintenance, replacement of spark plugs of a LADA Vesta with a VAZ-21129 engine (106 hp) is indicated.

How to change spark plugs with your own hands

Replacing spark plugs on a Lada Vesta 1.8 liter is no different from the 1.6 liter modifications. All actions are similar - only the engine size is different. The Lada Vesta SV Cross spark plugs are replaced in the same way. Engines of the same type are serviced equally.

The principle of replacement is as follows.

1. Place the car on a level surface and allow the engine to cool. All manipulations with the power plant occur only when it is cold. During operation, the internal combustion engine becomes very hot, which can cause burns.

   

2. When replacing spark plugs on a Lada Vesta, the ignition key must be removed from the cylinder and the power line blocks must be completely disconnected from the battery.
3. Prepare the keys and a set of new spark plugs. Typically, buyers prefer to use standard, factory-mounted ones or those with an iridium core.
4. Open the hood and pull the plastic engine cover. The decorative panel is installed with latches and can be easily removed.

   

5. The next step is dismantling the coil. The first step is to disconnect the wiring from the terminal pin by pressing on the block. Next, you will need to release the head and unscrew the screw securing the ignition coil. After which the part can be removed from the well.

   

6. You will need to use a special head to unscrew the spark plug from its seat. Some experts recommend using a wide wrench - due to constant overheating, the spark plug may jam or stick to the block head.

   

• Often the candle refuses to come out of the well. You can get it out of the shaft using a short circuit, putting it on top of the unscrewed part.

  

• Installation of a new spark plug must be carried out strictly in the reverse order. In this case, the device must be driven into the thread by hand, and only then tightened.

It is noteworthy that the plant categorically does not recommend using a torque of more than 25 N*m - this can damage the cylinder head.

The video will tell you more clearly how to replace spark plugs on a Lada Vesta.

Replacing spark plugs on a Lada Vesta is no more difficult than on other cars. The procedure does not require specific equipment, tools, or deep knowledge of mechanics.

When to change spark plugs on Vesta

In accordance with the maintenance and operation manual for LADA Vesta, replacement of spark plugs (SZ) should be carried out after 30,000 km of vehicle mileage or once every two years of vehicle operation (MOT 2), depending on the event that comes first.

Signs of spark plug problems may include:

• self-detonation of the fuel mixture in the fuel combustion chamber;
• a sharp drop in engine power;
• sudden heating of the catalytic converter;
• increased gasoline consumption.

Significance of the ignition system

The importance of the ignition mechanism of the combustible mixture in the operation of internal combustion engines can hardly be overestimated. That is why replacing spark plugs on a Lada Vesta must be done in a timely manner. Do not forget that their unsatisfactory condition can cause:

• Detonation of the mixture in the combustion chamber.
• Reduced motor power.
• Overloading and heating the catalytic converter.
• Excessive consumption of fuel.

Problems with spark plugs can also signal problems in other vehicle systems. For example, a product with obvious traces of oil on the electrodes, especially on the threaded part, indicates the unsatisfactory condition of the oil seals. Unfortunately, the first reviews of the Lada Vesta pay more attention to the exterior and driving comfort than to technical problems.

Characteristics of candles

Spark plugs for 8 and 16 valve engines are different.

The service life of candles does not particularly depend on the manufacturer, since we are not talking about stuffed technological equipment. In our case, this is a piece of metal of the correct shape with dielectric elements of the body. If the spare part meets certain requirements, then there is no need to fool your head.

Main characteristics:

• They should not lose their insulating properties at temperatures of a thousand degrees;
• Without interruption, they must provide a stable voltage of 40 kilovolts;
• Resistance to thermal shock;
• The metal must withstand chemical reactions at the installation site;
• The thermal conductivity of electrodes and insulators must comply with the standards.

When replacing, visually compare the old and new spark plugs.

Which spark plugs to choose for Lada Vesta: factory opinion

According to Lada Vesta owners, NGK BCPR6ES spark plugs would be an excellent choice.

For an 8-valve engine : 14R-7DU–Ber, RN9Y–Champion, BPR6ES–NGK, W20EPR–Denso, LR15YC-1–Brisk, WR7DCX–Bosch.

For a 16-valve engine : AU17DVRM, DR15YC-1–Brisk, FR7DCU–Bosch, Q20PR-U11–Denso, BCPR6ES–NGK.

The question, of course, is not the name of the manufacturer, but the design features.

The wrong choice of these elements will lead to the fact that they either do not work or will not work.

In addition, for the first option, a regular spark plug wrench is suitable, and for 16-valve models, a reduced size hex wrench is suitable.

Repair procedure

Checking the gap. It should be equal to 1.1 mm

The spark plug gap on the 16-valve Lada Vesta is 1.1 mm.

The process is completely simple if you have the necessary tools. After dismantling, you can assess the presence of a gap between the electrode contacts. Maybe you can just adjust the gap there and there won’t be a need for replacement, but if our 30 thousand kilometers are already behind us, then throw it straight into the trash.

During installation, the engine must be turned off and cooled to ambient temperature.

We will also need a TorxE-8 wrench, 16 head. When replacing an element, it is important to tighten it well, but not excessively, so as not to break the thread. After 30 thousand we will have to repeat the procedure.

One small but important reminder. You need to wrap the candle with your working hand so that you can feel when it goes along the thread. If something happens, you can stop in time by starting the process over again, carefully cleaning the threads. That's all, you can drive until the next replacement.

Features of igniters for 16-valve VAZ 21129 and VAZ 21179 engines

Vesta is produced with a 16-valve engine. Let us dwell separately on sixteen-valve engines. Technologically, they are more complex and sensitive to the choice of fluids, and require greater oil consumption.

We have listed the types of ignition devices that are needed for a Vesta car. By following the rules, you will ensure your car has a long service life and will be able to save on repairs in the future.

Selecting replacement spark plugs for engines installed on Lada Vesta requires several parameters, and replacement regulations are difficult to systematize. The fact is that the life of spark plugs on any car depends not only and not so much on their manufacturer, but on the quality of the fuel, engine settings and the degree of wear. Nevertheless, AvtoVAZ gives an average schedule for replacing spark plugs - 30,000 km. What spark plugs are best to put on the Lada Vesta, when and how to change them, we’ll figure it out together.

Obvious signs of wear - you need to know

Spark plugs are a device for igniting gasoline. Lada Vesta is equipped with a 16-valve engine, that is, a spark plug set of 4 units is required.

We list the main signs that the spark plugs on a Lada Vesta need to be changed:

1. The starter operates with a delay, after several idle revolutions; 2. The ride of the car is not smooth, but with noticeable jerks; 3. Motor dynamics decrease; 4. Fuel consumption per 1 sq. km increases; 5. The color of the exhaust gases changes.

Spark plug sets for the 16-valve Lada Vesta are produced by different companies - both Russian and foreign.
