Good spark plugs for Lada Kalina

About candles

The spark plug in the engine is a very important element, without which the internal combustion engine simply will not work. At the moment the spark is applied, the fuel mixture in the combustion chamber is in a compressed position, when a spark appears, the mixture ignites and an explosion occurs, thereby pushing the piston down. The spark plug serves as a link between the ignition coil and the combustion chamber.

The difference between candles

Two types of engines with 8 and 16 valves were installed on the Lada Kalina. The type of spark plugs depends on the number of valves. The difference between the spark plugs in a 16-valve engine is the smaller diameter of the hexagon, since these spark plugs are placed in the spark plug well, where there is a rather narrow distance from the walls, which does not allow the use of spark plugs with a 21mm hexagon.

Spark plugs from a 16-valve engine can be installed on an 8-valve engine, but vice versa will not work, spark plugs from an 8-valve engine will not fit into the spark plug well.

Candle device

Kalina standard spark plugs

The manufacturer installs spark plugs of type AU17DVRM from the assembly line. These candles have proven themselves well and are quite reliable. There are also a large number of imported analogues that are in no way inferior to domestically produced candles.

Below is a table with candles that are perfect for Lada Kalina.

When is it necessary to replace spark plugs?

The replacement of spark plugs is carried out no later than 40,000 km, since by this mileage the wear of the insulators on the spark plugs is already quite decent, and the temperature may increase the gap between the contacts, which will lead to incorrect operation of the spark plug.

You should also first replace the spark plugs if misfires are detected in the cylinders or unstable engine operation, interruptions in operation and loss of power.

The best candles for Kalina

Spark plugs NGK No. 11 for Lada Kalina
To summarize, I would like to add that according to the results of surveys on forums, the majority of car owners gave their preference to spark plugs NGK No. 11 and AU17DVRM. These candles from a Japanese company and a domestic manufacturer showed their best performance and received their well-deserved place in the ranking of the best candles for Kalina.

According to reviews, NGK spark plugs easily survived up to 50,000 km, of course, these figures can be either more or less, it all depends on the operation of the car and the fuel used, but the fact remains a fact.

Choosing spark plugs for the engine 21116 and 21126

According to technical regulations, spark plugs in engines 21116 and 21126 should be changed during maintenance-2, that is, after 30 thousand km. In fact, this period can be extended by one and a half times if we are talking about gentle operation. But you shouldn’t do this if the car is under warranty (then the replacement is carried out according to the regulations). Here we will list which spark plugs are suitable for each of these engines. We will assume that the owner of Kalina-2 uses the catalogs of the following companies: BERU, CHAMPION, NGK, DENSO, BRISK, BOSCH.

AvtoVAZ’s recommendations for choosing spark plugs look like this:

JSC ZAZS (Russia) – AU17DVRM, A17DVRM;
BERU (Germany) – 14FR-7DU, 14R-7DU;
CHAMPION (England) – RC9YC, RN9YC;
NGK (Japan) – BCPR6ES, BPR6ES;
DENSO (Japan) – Q20PR-U11, W20EPR;
BRISK (Czech Republic) – DR15YC, LR15YC;
BOSCH (Germany) – FR7DCU, WR7DC.

On the left is the brand of the product suitable for a 16-valve engine, on the right is for an 8-valve engine. You may notice that spark plugs with thin electrodes, iridium, etc. were not listed here. A thin electrode is then used to ensure reliable ignition at high speeds (7,000, 8,000 rpm or more), but for VAZ engines above 6,000 rpm the cutoff is triggered. Iridium spark plugs have a thin central electrode in their design, but as we have already found out, switching to using such parts is a waste of money, and nothing more. The durability of iridium spark plugs approximately corresponds to the “lifespan” of a spark plug with a standard copper electrode. We leave the choice to the owner.

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. Depending on the number of cylinders of the car, the number of spark plugs changes. Let's consider the components of the system design and their functionality:

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. There are many myths that iridium products significantly increase the performance and power of car engines; in practice, the increase in efficiency is not large. Let's look at the best types of glow systems in a little more detail:

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.

Ceramic deposits have appeared - change the spark plugs immediately!

In terms of their operational parameters, including durability, all components of the listed items are almost the same from each other. This is confirmed by reviews from car owners expressed on various forums, etc. Perhaps there are more expensive components, the use of which will allow a simple replacement to increase power, engine torque or some other characteristics. But having installed such spark plugs in the 21126 engine, you will most likely have to forget about the warranty on the AY-K3 gearbox. It’s always like this with technology: we need to imagine what exactly we are doing and what we want to achieve as a result.

Selection of spark plugs for modern VAZ engines

Indications for replacing spark plugs:

If there is black soot (“suede”) on the insulator cone and electrodes, then cleaning or replacement can be done. Cleaning is carried out, among other things, by heating. When replacing, it is better to use spark plugs with a slightly lower heat value than before;
If the surface of the insulator looks like yellowish glossy ceramic, then the spark plug needs to be replaced. In this case, a glassy glaze is formed. It is electrically conductive.

In the first of the cases considered, carbon deposits are formed because not all elements of the candle are heated sufficiently, and self-cleaning does not occur. This can happen when the car is used for short trips with low speeds and frequent starts and stops. The same effect is typical for operating the motor at low temperatures. Logically, in such situations, the recommended replacement would be a spark plug with a lower heat rating than what was intended by the manufacturer. You can try installing A14DVRM spark plugs instead of A17DVRM in an 8-valve engine, and so on. Only now, such a replacement must be discussed with the dealer.

QUESTION ANSWER

— What do the terms “dry” and “wet toxicity” mean?

These are slang terms for engine specialists. Raw toxicity is the one immediately after the engine, before the converter. Dry - after the neutralizer: what goes into release.

— Why do we need different spark plugs if the neutralizer still burns out the unburnt mixture?

It does not burn out everything (in terms of CH and NOx - up to approximately 30–50%). Therefore, the greater the raw toxicity that the candles affect, the greater the dry toxicity. Moreover, the neutralizer does not successfully extinguish toxicity in all modes: in particular, when the mixture is enriched, that is, during acceleration, start-up, and heavy loads, it also does not work effectively. And the neutralizer does not affect power, starting and fuel consumption at all.

— A modern controller reacts to missed flashes by lighting up the Check Engine. How does the neutralizer respond to this?

The neutralizer does not react in any way to missed flashes. At least you won't see it in diagnostics. If the process is too started, we will get a decrease in its service life and, possibly, early failure. The residual oxygen sensor reacts to leaks: it catches excess oxygen not used in the cylinder and gives a signal to enrich the mixture.

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.

Step by step replacement

1. First, disconnect the negative terminal of the battery. Ten key nut.

2. Remove the engine protective cover. We just pull it towards ourselves.

3. Using a socket head, unscrew the fastenings of the ignition coils. Each coil is secured with one bolt.

Ignition coil bolt locations.

4. Remove the power connectors from the coils. On the connector, press the latch with your thumb and pull it towards you.

5. Take out the coils. They fit tightly, so you need to apply some force.

We stack the coils so that we remember where each one was. During assembly you need to install it as it was.

6. Unscrew and change the spark plugs. I advise you to change one spark plug at a time. That is, they unscrewed one spark plug and screwed in a new one.

If you unscrew all the spark plugs at once, there is a chance that debris will get into the wells.

We tighten the candles without fanaticism.

7. Insert the coils all the way and tighten them with bolts.

8. Connect the connectors and battery terminal.

9. Put on the motor cover.

There are four grooves on the cover, and four matching holes on the motor. Just put the grooves into the holes and press.

Which brand is better?

As a rule, LADA Kalina owners prefer spark plugs in the mid-price segment. These traditionally include domestic products from EZ

(placed on the assembly line) and Czech
BRISK
.
NGK
spark plugs
Denso
equivalent .
The reliability of original Bosch
extends their service life - they last much longer than the period for routine replacement.
BERU
are also trustworthy - despite the attractive price, the igniters behave excellently in VAZ engines.

High-quality brands may have one indirect drawback - the presence of counterfeit products on the market. There are only two ways to combat this - carefully study the product and packaging, and be selective in choosing a supplier. It is better to trust a well-known retail chain with a reputation or official representatives of the brand. In this case, the likelihood of acquiring a counterfeit product is minimized.

Which spark plugs for Lada cars are best to choose?

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:

Granta, Kalina, Largus, Vesta

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 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.

Tips for choosing spark plugs for Lada Kalina

The choice of igniters for the LADA Kalina engine is not particularly difficult and largely depends on the size of the budget allocated for replacement. There are a few key features to consider when making your purchase:

Heat number.

Based on this parameter, it is recommended to choose medium spark plugs (15-19) for the Lada Kalina. If you take a cold one (14 and below), then not only an improvement in spark formation will be observed, but also overheating of the igniter. If the quality is low, the candle will quickly fail. A heat rating of 20 or higher in 1.6 engines leads to misfires and carbon deposits.

Dimensions.

These values must be strictly observed:

Material of the central electrode.

Affects the quality of spark formation and the durability of the spark plug. Copper and nickel cores are the most common. Yttrium alloy demonstrates increased throughput at a low price. The most expensive spark plugs come with electrodes coated with platinum or iridium - they are durable and reliable in any conditions. Their service life depends on the model and can range from 60 to 120 thousand km.

Top 5. BERU Z21 (14R-7DUX)

The low heat rating and high conductive characteristics of the materials used in the BERU Z21 spark plug contribute to the reliable operation of the internal combustion engine. Lada Kalina shows excellent dynamics even with a very lean fuel mixture.

Average price: 144 rub.
Country: Germany
Electrode: yttrium
Gap, mm: 1.1
Heat number: 7
Resource, km: 30000

An excellent choice for LADA Kalina owners instead of factory spark plugs. The service life of BERU igniters more than covers the replacement interval recommended by the car manufacturer. The use of the latest developments in the field of conductive materials gives spark plugs the ability to confidently work with very lean mixtures. After installation in a Lada Kalina with a 1.6 liter internal combustion engine with 8 valves, smooth operation at idle and no misfires at high speeds are observed. This has a positive effect on acceleration dynamics. Among the disadvantages - 14R-7DUX is not always on sale; for a planned replacement it is better to order spark plugs in advance.
