Representatives of AvtoVAZ assure that the build quality of Vesta is constantly improving. Reviews from owners to some extent confirm this fact. Let's look at how spark plugs behave, among other equipment.
It must be said that Vesta has problems, for example, with not particularly modified wipers, punctures occur with the gas pedal, and there is no corrosion treatment for the bottom. Complaints about deficiencies in power mechanisms are extremely rare. Therefore, it is premature to talk about repairing any element of the fuel system.

Types of candles, their structure
Not enough horsepower during acceleration, slow start, fuel consumption is growing at a gigantic rate, is the car shaking? You need to take a closer look at the heating system. These failures can occur for other reasons, but they are the clearest sign that the ignition is not working properly.
- top terminal: ignition coil connection point;
- main body: high voltage generation and heat insulator;
- thread: screwing a product into the cylinder head;
- electrode: spark source, the most important element, the quality of the system depends on its reliability.
It is important to know the difference between the two existing types of glow systems - spark plugs and glow plugs. The former are used by vehicles with a gasoline engine, and the latter by vehicles with a diesel engine. A standard feature of both options is engine starting assistance. We list several main characteristics of the system:
- center contact material;
- spark gap size;
- heat number (the higher it is, the less the product heats up);
- overall and connecting dimensions (length and thread pitch);
- number of side electrodes;
- resource of use;
- self-cleaning ability.
There is a variety that has become very popular - iridium spark plugs. Theoretically, their design has a thinner central wire diameter than others, it conducts current better and generates a more powerful spark, which greatly simplifies engine operation.
- Heaters perform the same function in diesel engines as the ignition system in gasoline engines. They are called "preheat plugs". They are responsible for facilitating cold starts, which is especially important for diesel engines, which are increasingly found on our roads. The heater is a resistor designed to increase the temperature inside the combustion chamber. Its shape resembles a ballpoint pen, one end of which is heated before starting. It is important to remember that it is advisable to replace all elements at the same time so that the work is rhythmic.
- Plugs are elements that ignite a mixture of gasoline and air inside the combustion chamber. A spark is generated due to a difference in electrical potential. If the motor is operating normally, this process is repeated an average of 2000 times per minute.
If you replace the ignition system in time, you can avoid premature wear of other parts of the vehicle. If you notice any of the following signs, it's time to consider purchasing new devices:
- loss of power while driving;
- increased fuel consumption, because gasoline combustion occurs incorrectly due to a spark generated at the wrong time;
- difficulty starting, especially in cold weather, knocking when the engine is running;
- dark smoke on the exhaust.
Let's look at the process of attaching a new heating system, provide step-by-step instructions and tips for installing the product yourself at home.
Replacing spark plugs and the need to adjust the factory manual
As mentioned earlier, the replacement of ignition system consumables is carried out within the framework of routine maintenance procedures, which is recommended by the plant at 30 thousand intervals.
However, if the equipment operates in difficult conditions, then the time required for both maintenance and replacement of consumables should be halved.
As for the very definition of difficult conditions, these are:
- frequent trips within the boundaries of large metropolitan cities over short distances;
- prolonged driving at low speeds;
- driving in dusty or sandstorm-prone areas;
- frequent trips with a trailer or when the Lada Vesta is heavily loaded.
Well, one more thing about the features of replacing spark plugs is that on engines with an 8-valve timing system, access to spark plugs is much easier than to the actuators of the ignition system of 16-valve engines.

| Igor June 9, 2022 at 12:56 pm | Hello! The price is for one candle, or a set? Reply |
| / Administrator / June 9, 2022 at 06:12 pm | Good afternoonPrice is for 1 piece, see the description. Iridium spark plugs for a set at such prices do not existReply |
| / Administrator / June 13, 2022 at 04:09 pm | The price doesn’t seem to vary that much. The main difference is that according to the article number in the news, the ones recommended are the ones we sell. They have already been tested by vestavods. Read on the drive, there are a lot of discussions about which ones are better to install. It’s better to take the IK-TT modelReply |

You shouldn’t compare our prices for spare parts with aggregators, for a number of reasons: 1) Aggregators have obviously lower prices, because They do not keep items in their warehouses, but pull them from suppliers’ warehouses for a specific order. 2) In aggregators, counterfeits are often found for a number of items, because There are a lot of suppliers, no one monitors quality 3) By definition, we cannot get the same discounts as aggregators, because we buy on a completely different, smaller scale. It’s not a matter of greed, but somewhere in quality, somewhere in economies of scale. For plastic, which we sell a lot and which is our main specialization, we try to maintain the best prices. Next is your choice with candles and everything else. Order Gates belts from some auto retailer, and then prove that they are 2 times cheaper there by paying for the capital of the engine after the timing belt breaks. Reply |
| / Administrator / May 23, 2022 at 08:44 | Good afternoon. This is not about a VAZ recommendation, but about a DENSO recommendation. Before introducing it into the assortment, we wrote them an email asking which spark plugs are best for the VAZ engine for Vesta and Xrey, they gave this exact article numberReply |
| Minnigaliev Ramil Airatovich May 24, 2022 at 1:26 pm | The factory recommends a gap of 1..1.15 mm. These candles have 0.95 mm. After replacement and several trips (about 50 km) in comparison with the new relatives (4400 km): 1. XX is a little smoother 2. Slightly more vigorous from 1000-1500 rpm, but the difference is barely perceptible (possibly a placebo) 3. At work there is no difference in rpm 4. Consumption at XX according to the BC remained the same 0.7-0.9 jumps. Well, maybe just a little 0.7 more often. Conclusion: there are no really noticeable improvements in comparison with the new ones, and the price is almost 10 times more. If they use 2-3 times more resources than their relatives, then it’s not a pity, I don’t want to mess with the engine once again. Site administration: look at these BRISK PREMIUM P2 DR15 YIR-1 spark plugs. Iridium, declared resource 100,000 km. The gap fits perfectly with AvtoVAZ's recommendations and costs more than 2 times less. Reply |

| Minnigaliev Ramil Airatovich June 16, 2022 at 12:23 | In general, I tried BRISK PREMIUM P2 DR15 YIR-1. It feels like there is no improvement compared to the factory ones. But the Denso IQ20TT is really the best choice for Vesta, most likely - it is smoother at idle and better at the very bottom, and there is practically no jerking when driving at idle in 1st gear.

Out of curiosity, tell me, what has ever happened to you with candles in your car that you ask such questions? If there are no problems with the engine, then regular spark plugs last for 30 thousand, but iridium spark plugs do not change without problems for more than 70 thousand if the engine is working properly. There are, of course, people who roll them up to 200 thousand, but the manufacturer does not recommend more than 100 thousand kmReply |

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.
They have 4 valves per cylinder (a total of 16 valves), therefore fuel consumption is reduced and engine power is increased by 15-20%. In the 16-valve VAZ 21129 and VAZ 21179 engines, BCPR6ES and FR7DCU (manufactured by NGK and Bosch, respectively) are good options for replacing these spare parts. Models from well-known companies Denso, Brisk, JSC Robert Bosch Saratov.
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.
How to choose the right spark plug
It is important to purchase high-quality spare parts for a car; in order to buy a good product, you need to pay attention to the following selection criteria:
1. It is necessary to order a product compatible with the machine's engine. Most of the best brands clearly indicate the vehicle models their product will be compatible with. Therefore, you need to carefully review the manufacturer's compliance list.
2. Apart from compatibility, you need to choose the design type as there are various options available. The most common:
- Copper-Nickel: The name may confuse you because these products are primarily made of nickel, with only the inner core being made of copper. It conducts current well, which is why most electrodes are made from it. The product is inexpensive, its disadvantage is that it has a short service life, even if used in a high-energy ignition system without a distributor. Many vehicles will benefit from this option; it is suitable for natural gas engines.
- The next type has a platinum center contact. It is expensive due to the rarity of this element, which is harder than nickel, so you can be sure that the product will not corrode. The platinum will prevent the tip gap from widening and wearing out, which directly affects the efficiency of the engine. There are models with one or more electrodes. This helps generate the spark in the best possible way. In terms of service life, it is twice that of standard nickel/copper construction.
- Iridium Product: If you want flawless, smooth motor performance, there is nothing better than an Iridium product. It has a longer service life than traditional models. The thin wire central contacts are designed to conduct current most efficiently. These are expensive products, but the price is offset by incredible performance.
- Silver candles are an option with the best thermal conductivity. The problem with this product is its durability. The precious metal cannot match the durability of platinum or iridium models.
New Lada: Gearbox JH3, JR5, 21809 Lada Largus / Lada Largus
All designs fit any vehicle in one way or another, but the platinum-based option is more universal. It is relatively affordable than iridium and much better in performance and durability than copper-nickel devices.
3. It is important to decide: “What kind of ignition is needed, cold or hot?” To give a very simple but precise definition, we can say that candles that glow during operation are hot. And those that do not reach high temperatures are cold.
The metal shell of the structure operates at the same heat as the head. The elements are screwed together to form a chamber in which heat is distributed evenly. Hot models have a long insulator tip with a large surface area, causing all parts to become hot. At the same time, cold ones have a small cap that helps quickly remove excess degrees from the combustion zone.
Russian-made models usually have a numerical heat rating. Their assessment is not always consistent because some brands give higher values while others underestimate.
It becomes extremely difficult for buyers to choose the right product with so many options. It is best to order the design in accordance with the car's engine and year of manufacture.
4. If you do not want to suffer for a long time during replacement, it is better to choose a design that is easy to install. Using the above selection criteria, you can easily determine a productive model.
Below is a table of compatibility of spark plugs for a Lada car:

Which spark plugs for Lada cars are best to choose?
08 October 2022 Lada.Online 368 323
A malfunction of the spark plugs immediately affects the operation of the engine; it begins to stall, jerk, does not pull, or starts poorly. To solve the problem, simply replace them with new ones, but which spark plugs are better to choose?
All modern 8 and 16 valve power units have the same manufacturer's recommendation. In other words, advice on choosing spark plugs will be similar for all modern Lada cars.
In the user manual for Lada Priora, Kalina, Granta, Vesta Largus, Niva and XRAY cars, the engine technical specifications contain the following data:
| Engine | VAZ 11183, VAZ 11186/11189 | VAZ 21126, VAZ 21127 | VAZ-21214 | VAZ-21129, 21179 | HR16/H4M | K4M/K7M |

| FINWHALE | F510 | |||||
| Renault | 224011561R 224019372R | 7700500168 |
The gap between the spark plug electrodes should be within 1...1.15 mm. Let us remind you that Lada Vesta and Lada XRAY can be equipped with a Nissan-Renault HR16/H4M engine. The spark plug gap in this case should be 0.85...0.95 mm. For K4M/K7M engines (more about spark plugs), the gap between the spark plug electrodes is 0.95 -0.05.
According to the requirements, the manufacturer must guarantee uninterrupted operation of the spark plugs for 18 months, provided that the vehicle mileage does not exceed 20,000 km. However, with good technical condition of the engine and proper operation, the service life of the spark plugs can be significantly longer. Thus, spark plugs are often replaced every 3 years or after 40 thousand km.
Marketers suggest improving engine performance by installing, for example, iridium, platinum or multi-electrode spark plugs on the Priora, the price of which is higher than usual. AVTOVAZ recommends using conventional, single-electrode spark plugs for its engines. In a review by ZaRulem magazine, a survey was conducted that shows that the majority of drivers follow the factory’s recommendations and choose simple, inexpensive spark plugs.
As part of the same review, nine different spark plugs were tested. As a result, they all passed the tests, and the winner was determined by summing up the points:
So what spark plugs should I put on the Priora/Granta/Kalina/Vesta? Based on the recommendations of AVTOVAZ, the test results of a popular car magazine and a survey of the social network VKontakte, we can conclude that the best choice would be spark plugs from manufacturers: NGK, Bosch, Denso, Brisk and EZ Standard.

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.
Sometimes the condition of the ignition device can indicate problems with other parts of the vehicle. For example, if the thread of the spark plug hole contains traces of oil on the electrodes, this means: the oil reflective caps have exhausted their service life. The service station staff will advise you when to replace the igniters. However, this period is also determined by the brand, and it can be found out from the factory operating instructions.
Spark plug sets for the 16-valve Lada Vesta are produced by different companies - both Russian and foreign.
Replacement procedure
Any murzilka (operation book) for VAZ cars states that spark plugs must be replaced every 30 thousand km. mileage However, in practice, even the highest quality products rarely travel 30,000 km.
The first sign that a replacement needs to be made is a change in the normal functioning of the engine. You will notice changes in its idle speed, and there will also be problems with ignition.
Unscrew them and visually inspect the electrodes. In normal condition, the electrodes are light gray in color, with a minimal amount of brown deposits allowed. During operation, the electrodes become covered with a yellow or brown coating (this is a normal condition for the middle of their service life).
It is also necessary to pay attention to the spark plug gap between the insulator and the electrode (ideally for Priora it should be 1.1 mm, which is indicated in the service book). The gap increases during operation, so if a check shows that the gap is 2-3 millimeters larger than it was originally, the spark plug needs to be replaced.
The gap can be adjusted by simply bending or pressing the electrode against the insulator, but this can only be done normally on new spark plugs; when worn, the electrode, as a rule, becomes very fragile and crumbles under rough influence.
In the image below you can see the stages of spark plug wear.
Stages of spark plug wear
If the electrode is intact, you can try to revive the product; to do this, you need to anneal the deposit on the electrode with a gas burner and, after it has softened, remove it with a metal brush. This must be done carefully so as not to damage the fragile structure.
Now let’s figure out how to replace spark plugs on a 16 valve Priora. To do this you will need a spark plug wrench, a screwdriver and a 10mm socket wrench to unscrew the coils.
Everything is done according to the following algorithm:
- Open the hood and remove the plastic protective cover from the engine;
- We remove the power wire from the ignition coils and unscrew the bolts that secure them;
- We pry up the coils with a flat screwdriver and take them out;
- We take a special key and unscrew the spark plugs. This may not be so easy to do, since high temperatures may cause the shrink thread to stick to the body of the part. Unscrew it carefully so as not to damage the structure, since removing fragments of insulator from the well is an extremely problematic task. If you have a compressor at hand, blow out the shrinkage well to remove dust and contaminants accumulated in it;
- We check the condition. If it is damaged or extremely worn, we install a new one. We insert the spark plug into the magnetic head of the key and screw it back in. There is no need to make any effort here - the thread should go smoothly, and after the body is held tightly in the seat, you need to tighten the thread with light force;
- All that remains is to install the coils in place and connect power to them.
Replacing spark plugs on an 8-valve Priora differs from the procedure described above due to their location. In 16-valve engines they are recessed into a well inside the cylinder block, while on 8-valve engines the spark plugs are placed on the surface of the block, so changing them is much easier.
Replacement is carried out as follows:
- Remove the power wire from the shank;
- Unscrew using a 21 mm socket wrench;
- Screw in new ones and connect power.
Now you know which spark plugs are best for Priora and how to replace them. Have a good ride without any breakdowns!
Established rules for replacing spark plugs on a Lada Vesta car
Scheduled maintenance on the 2180 includes replacement of igniters. The operating regulations for classic devices indicate the following update frequency: every 30 thousand km (15 thousand km with high mileage). And iridium and platinum ones need to be updated every 100 thousand km.
In addition, the condition of the engine may indicate the need for urgent replacement. If cracks appear on the ceramic part or the insulator has peeled off from the metal part, then it is time to replace the entire ignition system.
