If malfunctions in the VAZ-2190 begin to manifest themselves, associated with poor engine starting or unstable operation, then the probable cause of these unpleasant moments may be the fact of wear of the spark plugs. This factor is especially clearly manifested on 8-valve Lada Granta units. To save yourself from the risk of stopping on the road, you need to regularly check the functioning of the ignition system. Many car owners are interested in the question, which spark plugs are better?
About aspects of the ignition system
In the engine compartment of the Lada Grant there is a 1.6-liter 4-cylinder engine, the design feature of which is the presence of both an 8-valve cylinder head and its 16-valve version. Depending on the type of valve mechanism used, the power indicator is equal to 82 hp. With. or to 106 “forces” respectively.
The control module is designed to monitor the correct functionality of the ignition circuit. This device receives certain impulses sent by sensors and processes them. The ECU then generates a voltage that is subsequently addressed to the coils.
For different valve mechanisms, the coils have their own design and location configuration. So in 16-valve variations of LADA Granta engines, these components are located in separate wells, the number of which is “4” (according to the number of cylinders).
For 8-valve units, the manufacturer used a single-casing design, which is essentially a step-up transformer. This device is equipped with a single primary winding with a middle location of its output and two secondary ones, whose output contacts are connected to spark plug tips. The ignition circuit of the Lada Granta, which has an 8-valve timing unit, has a so-called “idle” spark method. The essence of the declared technology lies in the synchronous generation of a spark in two cylinders at once. In the first of them (conditionally) it ignites the mixture and is considered “working”, and in the other it “skips in idle mode”.

What is the algorithm in the operation of the ignition unit?
By means of spark plug electrodes, a spark is generated in the combustion chamber, which allows the mixture to ignite. The operation of these components involves harsh conditions involving exposure to very high thermal and electrical loads. The temperature indicator of the spark plug electrodes of working spark plugs can reach 900 degrees. In the Lada Granta ignition system, the spark plug arc discharge, which generates a spark, is characterized by a potential of 30 - 40 kV.
The severity of the operating mode of these elements directly affects the resource. Also very common is the appearance of carbon deposits on electrode surfaces, which is caused by disturbances in the combustion process.
We should not forget an important point related to the detrimental effect of unit overheating on the life of most components of the ignition circuit. It is candles that are subject to increased requirements in terms of ensuring the ability to function under conditions of increased thermal disturbances.
The stability of spark production at the electrodes indicates the normal functioning of both the spark plugs themselves and other components of the ignition unit. To ensure trouble-free operation of system components, the following postulates should be strictly observed:

Grant's trunk
- spark plugs are replaced only with those consumables that are approved by the regulatory requirements of AvtoVAZ;
- exclude violations of the frequency of replacement of components (the duration of operation of one set should not exceed 30 thousand km);
- perform maintenance actions with the required regularity;
- tend to use motor oil and fuel only capable of having high-quality conditions.
Replacing a spark plug, all steps
It is usually recommended to replace spark plugs “one at a time”. But you can skip this requirement if you are not afraid of mixing up the wires. Each spark plug must be unscrewed with a 21 key.
Removing the spark plug (11186 engine)
A wrench with a high escutcheon or a tubular spark plug wrench will work here.
Installation is done as follows:
- Screw the candle in by hand;
- Taking the ratchet wrench, perform the final tightening. The torque should be 31-39 N*m.
Do not exceed the value stated here. This can damage the threads in the cylinder head cover!
Replacement and maintenance points
What are the best spark plugs? The manufacturer strongly recommends installing spark plugs on the VAZ-2190, version 8 valves that meet the standards of the AU17DVRM brand. These products are of domestic origin, or more precisely, they are manufactured at ZAZS Russia OJSC.
Catalog code – “21110-3707010-00”.
If we consider foreign analogues, we should highlight the following:
- "WD7DFC", produced by the German giant "BOSCH";
- “BCPR6” from the “ES-11” series from the Japanese brand “NGK”;
- "DR15YC" from the BRISK corporation (Czech Republic).
Each car owner decides for himself which spark plugs are best.
The entire set (4 pcs.) should be replaced. When choosing the parts you are looking for, pay attention to their technical characteristics. The following set of parameters will be relevant for a candle:
- diameter of the threaded section;
- its length;
- heat number.
The purchased spark plugs must fully comply with the needs of the LADA Granta engine in terms of the indicated characteristics.
Comparison of A17DVRM analogues produced under different brands
One of the online publications conducted a comparative test of spark plugs intended for the VAZ-21116 engine. We tested analogues of the A17DVRM spark plug, supplied by the following companies:
- APS, Bosch, Brisk – Russian production;
- Bosch Platinum, Beru, Finwhale – Germany;
- NGK, Denso – Japan;
- Eyquem - France;
- Champion – “made in the European Union”.
Note that testing was carried out on an 8-valve VAZ-2111 engine (injectors, lambda probe, without catalyst, “January-5.1”). All measurements were carried out on a bench.
Selection of spark plugs for 8-valve engine 21116
The results of the tests performed are presented in the photo in the form of graphs. As you can see, it still makes sense to buy imports: using spark plugs from Bosch, as well as products from the Finwhale, Brisk and Champion brands will provide a noticeable increase in power. If you want to save on fuel, then ask for NGK products in stores. Additional comments are unnecessary here.
Forced engines are characterized by an increased compression value, and VAZ engines are no exception. By installing Brisk spark plugs, you don't have to worry about sparking at high pressure. But note that NGK candles have similar characteristics. It turns out that NGK products should be considered the optimal choice, however, recently counterfeits of this brand have appeared. And the “remake”, it seems, is now coming from France, as described in the film.
If you have problems with the motor (for example, the engine started to start up badly, jerks or jerks), then start the search for the problem with the spark plugs. From their quality will depend not only on the cold start of the engine, but on the operation of the motor as a whole. And do you know what candles to put on Prioru / Kalina / Grant?
Recommended candles on Prioru / Kalina / Grant. The manufacturer recommends the use of domestic spark plugs A17DVRM and A15DVRM or their imported counterparts. Depending on the engine model, different spark plugs are used. For example, candles on Prioru 16 valves: AU17DVRM, and for 8 valves: A17DVRM. Compatibility table for spark plugs for all VAZ vehicles:

Kinds of spark plugs. Candles can differ in the number of electrodes: single-electrode (standard), multi-electrode. And also by type: Ordinary (regular), iridium, platinum. The manufacturer recommends using conventional single-electrode spark plugs for VAZ.
The service life of the spark plugs depends on the operating conditions. In accordance with the regulations for the maintenance of cars Lada Priora, Kalina and Grant spark plugs should be changed every 30,000 km. However, in some cases (for example, when starting the engine in a severe frost), it is possible to spoil the new spark plugs — pour them with gasoline. Advice: do not throw out old candles, but use them in such cases.
By the way, the owners of the VAZ of the tenth family in the poll “what candles to put” have allocated the best candles: NGK, Denso and Brisk. And the review / test of the spark plugs of the magazine Zarulm identified other leaders:

How to adjust the gap?
Performing maintenance involves cleaning the electrodes from accumulated carbon deposits and adjusting the gap. This parameter should not be allowed to exceed the manufacturer’s permissible requirements. The process of the spark plug involves reducing the height of the central electrode with the simultaneous formation of a rounded depression on the inner sphere. This implies an increase in the gap, the value of which is subject to adjustment. It is set using probes and corresponds to the limits of 1.0 - 1.5 mm. If the gap is set correctly, the probe will penetrate between the electrodes with a noticeable tension.
Spark plugs for Lada Granta: what you need to know
So, let's start with the fact that although the stated average service life of spark plugs is quite long (usually at least 25-30 thousand km), in practice, simple spark plugs need to be changed much earlier. Often, experienced car enthusiasts recommend replacing every 10-15 thousand km, regardless of whether the car is operated on gasoline or has an LPG.
Let's move on. Having figured out when to change spark plugs, let's move on to which spark plugs are best to choose for Grants. First of all, the selection of spark plugs for the Lada Granta must be taken seriously, since different types of internal combustion engines are installed on this model.
If we talk about a simple 8-valve engine or more technologically advanced 16-valve units, you need to buy spark plugs according to the parameters, and not just according to the manufacturer. This means that it is not enough to simply buy spark plugs from NGK, Denso, Bosh, etc.
- First, when choosing, you need to take into account the size of the hex key, since there are spark plugs for 21 and 16 mm, the length of the threaded part is 26.5 and 19 mm. You also need to take into account the diameter, as well as the thread pitch (10, 12, 14 and 18 mm with a pitch of 1x25).
- The second parameter is the glow number of the spark plugs. The spark plugs also differ in this indicator, since the engines are different. In short, heat rating is the ability to withstand heat so that overignition and detonation do not occur.
In the case of a Lada Granta with an 8-valve engine, the recommended glow number of spark plugs should be 17. These are “medium” spark plugs with a heat number of 16-19. There are also “cold” and “hot” candles.
The surest way not to make a mistake is to decide to install the kind of spark plugs that are installed on the Lada Granta 8 valves from the factory: A17DVRM or BOSCH WR7DCX. However, not all drivers are satisfied with their quality and service life, preferring analogues.
So, as part of the catalog search, the factory catalog number for the spark plugs is 21110-3707010-00. Another option: 21110-3707010-03. In the list of analogues you can choose candles from BERU, CHAMPION, NGK, DENSO, BOSCH, etc.
Taking into account the fact that the Granta engine is 8 cl. simple (does not have a high degree of boost and compression ratio); in addition to well-known brands, it is quite possible to opt for less popular manufacturers (for example, WEEN, HOLA or Lada-Image spark plugs).
Main parameters of spark plugs for Lada Granta 8 valves:
- spanner size - 20.8 mm;
- heat number - 17;
- interelectrode gap - 1 mm;
- thread length - 19 mm;
- thread size - M14x1.25;
- electrode - simple nickel.
Let’s also add that many are trying to get more efficiency from the internal combustion engine by installing iridium spark plugs on the Grant. So, replacing spark plugs with platinum or iridium ones has virtually no effect on the power and performance of the engine. In fact, these expensive spark plugs are simply not needed on a simple 8-valve engine.
Clearing away cinder deposits
You should resort to this procedure if the need arises and cinder deposits have accumulated on the electrodes. Here we do not recommend using pointed objects made of hard steel. Use a wire brush with soft bristles or sandpaper. Alternatively, you can resort to cleaning using a chemical or thermal method.
Inspect the condition of the electrodes after 10 thousand km or earlier, if the engine prompted this by its capricious operation. If the intensity of use of a LADA Granta car is low, then inspect the spark plugs once a season (twice a year).
Replacing spark plugs is very common, and the owner of a Lada Granta is not provided with a full guarantee of the high-quality functioning of the system and, accordingly, the engine. Also, no one will undertake to claim that the new spark plug will withstand the regulatory service life of 30 thousand km.
We change spark plugs if the following circumstances occur:
- there were signs of a poor (not the first time) engine starting;
- the unit is troit;
- traction performance has deteriorated significantly;
- mileage exceeded its regulatory limit of 30 thousand.
Be aware of the risk of injury from high voltage traveling through the wires leading from the coil to the spark plug tips. An important element of the spark plug is replacing them, so it must be done carefully.
The meaning of a candle in a power apparatus
Thanks to it, a spark is formed. The spark contributes to the ignition of the flammable composition in the engine cylinders. This process occurs because a high voltage discharge occurs through the electrodes. And yet, how often should you change spark plugs?
Structure
They are formed by several components:
- Output element. Through it, the spark plug is connected to the high voltage line.
- Insulator. It protects against excessive heating. Its ribs prevent damage to the entire surface. And between the center electrode and the side electrode the impulse, the spark, moves.
- Special seal. It prevents fuel from penetrating from the combustion compartment into the engine housing.
Key Features
Here, the leading place in importance is occupied by the distance (electrodes). It is also called gaps
Its size affects the efficiency of ignition of the combustible composition. The wider the parameter, the higher the power of the generated spark. And with a high-quality spark, the scale of the ignition area will increase. This way, the engine in the car is guaranteed to run smoothly and fuel consumption is stable. How can you tell when it's time to change your spark plugs?
If the parameter is modest, then a premature spark appears. And at low voltages a breakdown occurs. As a result, the power and efficiency of the engine decreases.
The second most important is the glow indicator. It reflects the highest temperature loads. The usual indicators for domestically made products are: 8, 11, 14, 17, 20, 23, 26.
Western analogues have slightly different dimensions. These products come in two varieties: hot and cold.
After installing very cold parts with a powerful heat index, the self-cleaning of these parts will be poor. And the engine will work intermittently.
The frequency of replacements is influenced by the conditions and advice of specialists. Very hot ones can lead to glow ignition. The consequences of this are quite devastating. This looks like detonation.
Materials and potential
Before determining replacement frequency, you should classify these parts into two market categories:
The candle operates in an insulated block. Without removing it from there, it is difficult to study the degree of its wear. How many spark plugs are there in a car? Car manufacturers advise changing them during a regulatory technical inspection. As a rule, this is carried out at intervals of 10,000 - 15,000 km, this is the service life of the spark plugs. This operation is very relevant for a simple type. But often this parameter is applicable for products from the second category. Although replacing expensive spark plugs can also be considered as a way for service centers to gain some financial benefit.
The best factor to understand when to replace is condition.
Experienced car owners can calculate wear and tear by the number of kilometers. For example, replacement should be carried out every 20,000 - 30,000 km, this is the period for replacing spark plugs. The catalog of every decent manufacturer indicates specific times, or rather distance intervals. From the simple category they change after 20,000 km. How long do the best spark plugs last? Platinum products in the area of 99,000 km.
Set of preparatory actions
When carrying out operations with electricity, first disconnect the battery - you need to remove the negative terminal. The nut on the terminal is unscrewed with a flat wrench “10”. Next, if we talk about motor 11183, you need to remove the plastic cover.
Surprise in the form of plastic protection
The part itself needs to be pulled up, snapping off all the rubber supports one by one. It would be better to unscrew the filler cap first.
The 8-valve engines of the Lada Granta family are very similar, the difference in power is due to the use of different connecting rod and piston groups. Due to different SHPGs, the engine that Grant inherited from Kalina (11183) does not bend the valves. But valves 11186 and 21116 are bent. To prevent this from happening, we recommend following the technical regulations for servicing and replacing the timing belt.
If you lose the supports, it doesn’t matter, they can be replaced. Support number in the VAZ catalog: 21120-1008658-00 (or 01).
The next step is to disconnect the high-voltage wires. Each plastic tip can be removed by hand (see photo). It is simply pulled out by rocking the body from side to side.
Location of spark plugs and protective caps
Pull the tip up
If you lack skill, it will be easy to damage the wire itself. Be careful!
Tip: to avoid extra effort, you can lubricate your palm with machine oil.
The third step is to clean the space next to the well. Use available materials.
There should be no dust near wells
Let the motor look at least as shown in the photo.
Video “Visual instructions for replacing the SZ on a 16-valve engine”
After the clamps from all coils are disconnected, you need to unscrew the screws that secure them in place. To remove the bolts, use an E8 star wrench. When all the bolts are unscrewed, the coils can also be removed. Owners of cars with an 8-cl internal combustion engine again skip this step, but they need to disconnect the high-voltage wires from the short circuit.
The formation of deposits indicates oil leakage. If the carbon deposits have a velvety appearance, then you will need to diagnose the car or adjust the operation of the control controller.
In cases 1, 2 and 5, the spark plugs can be cleaned and used further. In 3 and 4, replacement of spark plugs is required. In the latter, it is better to install new candles, but if this is not possible, you can temporarily use the old ones after cleaning.
