Replacing spark plugs. NGK candles for Kalina Candles for viburnum 1.6 8 cl

Since my Kalina’s mileage has long exceeded 30,000 km, I decided to replace the factory spark plugs with new ones, although, to be honest, the factory ones still felt fine. In cold weather it started up to -20 the first time, and if the thermometer dropped even lower, then the second time. On idle speed Of course, the tachometer needle floated a little, but it was barely noticeable to the eye. In short, we could still drive, but since it is written in the Murzilka - change it after 30,000 km, then we will follow its instructions and recommendations.

It didn’t take long to choose a company, since most car owners speak quite well about NGK spark plugs, and the main thing here is not to run into a fake. If you have a 16-valve Lada Kalina, then you need to take NGK No. 11, and if you have a regular 8-valve engine, then No. 13. I’ll describe the whole procedure a little, maybe this information will be useful for girls or beginners.

The procedure for replacing spark plugs on a Lada Kalina:

Before this procedure, it is advisable to wipe everything well and clean it from possible oil stains or dust so that no debris gets inside the cylinder. Now we need either spark plug wrench, or a long head of 21 mm.

We remove the wires one by one, you will have to make a little effort, since they fit quite tightly.

Personally, the condition of the electrode was normal, there were no deposits, oil film or soot on them, the only thing was that there was a reddish coating. And this is also not very good and indicates that the fuel with which I fueled my Kalina contained iron-containing additives, the so-called ferrocenes. This can lead to misfire, loss of power and increased fuel consumption.

When we screw in new spark plugs, it is best to first tighten them by hand, and only then use a wrench. Advice for beginners: it is better to change them one by one: that is, first unscrew the old one and immediately install a new one, and so on for each cylinder. Although, it is quite difficult to mix up the wires! But I remember an incident with my father’s VAZ 2112 16-valve, when we put the wires on incorrectly and started the car - it worked like a tractor, all the cylinders were out of tune. After you have installed a new spark plug, put on the wire and carry out exactly the same operation with the remaining cylinders!

That's it! Tighten it better so that it does not allow air to pass through, otherwise over time it may tear out the spark plug along with the thread, then you will have to spend another certain amount of money on repairs, but do you need it? At the end of my topic, I would like to arrange a short survey about who uses which companies, besides NGK, and what are their impressions? Let's discuss in the comments below!

Today, many people install gas-cylinder equipment on their cars, since driving on gas is much cheaper and more profitable than driving on gasoline. The following spark plugs are suitable for such cars:

• French BERU Ultra 14R-7DU, they are not quite designed for gas, but still suitable;
• Ukrainian Plazmofor Super GAZ have good quality, but are inferior to imported ones;
• Czech Brisk LPG LR15YS Silver, the electrode of which is made of silver. They are cheap but non-toxic.
• German Bosch Platinum WR7DP - they have a thin electrode and an original design;
• Japanese NGK LPG LaserLine are quite expensive, but non-toxic and economical.

In general, there are a large number of them, the main thing is to choose models with thin electrodes for gas.

Criteria for selecting candles

Experts recommend not to take candles yourself if you do not understand this issue and also do not know
temperature regime your motor. In this case, it is better to consult a specialist from an auto repair center. He will help you choose a suitable part that will not only serve correctly, but also will not require constant repair or replacement.

As we have already said, with careful use, the spark plugs can not be changed for 3 years. That is why there is no need to save on these devices, otherwise after a short time you will have to spend money again on buying new candles. Do not hesitate to seek competent help, as it is better to get advice and buy a quality part than to take what is offered in the store and then regret your choice. In any case, service life depends on the conditions of use. It is advisable to change spark plugs every 30 thousand km.

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.

• 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. 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 in their design have a thin central electrode, but as we have already found out, switching to the use of 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.

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 box. 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.

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.

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.

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 Bosch spark plugs, 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. 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.

  Kalina 2 after 100 thousand km. mileage Is it worth...

My Kalina had already run a little over 40,000 km, and the factory spark plugs were still working normally, despite the fact that the manufacturer recommends changing them once every 30,000 km. Well, I think I’ll try to buy and install new ones, maybe something will change better side, but in principle it’s not better, everything was fine in my opinion.

I went to BB and picked up a set of NGK spark plugs. Since the engine on my Kalina is 8-valve, then for my engine there were No. 13, and if you have a 16-valve engine, then you need to use No. 11.

I unscrewed the old ones and looked at them, everything seemed to be fine, but they were too red, and this indicates, first of all, that the gasoline with which I filled the car contained too many iron-containing additives, which are not beneficial at all engine. Since I mostly refueled at one local gas station, I blame it. Now you have to change gas stations.

I screwed in the new spark plugs and decided to see how they would work and whether they would differ in any way from the factory ones. Kalina started up normally, after warming up the tachometer needle still barely noticeably floats, but if you don’t look closely, it’s simply impossible to determine the floating speed by ear. But when I started checking it at high speeds, I was pleasantly surprised, the sound became much softer and this is clearly not self-hypnosis, since I’ve been listening to my 8-valve tractor for two years now and I can certainly feel the changes. Judging by the feel, it began to somewhat resemble my previous car with the 1.5 16-cl. motor. But at idle the bubbling still does not stop, apparently there is no way to get rid of it.

So, while I'm happy with replacing the spark plugs, high revs now quiet and without unnecessary vibrations, as it was before. Let's see how high quality they are and how long they will last. So far so good.
