Stability of operation for a Chevrolet Niva car depends on little things: spark plugs

What do candles do?

As you know, a spark plug supplies a spark to the cylinder to ignite the fuel inside the combustion chamber. The spark plug is exposed to enormous temperatures, which of course does not have a favorable effect on its condition, so neglecting to replace spark plugs is highly discouraged and, if possible, it is advisable to change them before winter for easier starting in cold weather.

A worn-out spark plug can cause a lot of trouble, such as a lot of engine tripping, a number of misfires, loss of power and even an increase in fuel consumption.

In this article you will find the answer to the question of which spark plugs are best suitable for the Lada Niva.

DIY replacement instructions

To dismantle, first of all you will need a special key for removing the SZ. First you need to remove the ends of the wires from the spark plugs and clean all contacts from dust. The entire spark plug and the area around it must be thoroughly cleaned to prevent debris from getting into the cylinder.

Next, you need to remove the devices with a key and visually diagnose them for damage. You need to inspect both the electrodes and the threads. If there is noticeable darkening on the NW, it’s okay, but if there is no brownish coating, you should be alarmed. If black plaque is found, it must be removed. It indicates that engine oil has entered the engine cylinder.

Spark plug gap on Niva

The gap between the electrodes on the spark plugs is one of the main indicators that directly affects the operation of this engine part. It must be checked every 20-25 thousand km to ensure proper engine operation. The gap can be adjusted if it is out of the normal range or it is better to replace the spark plugs with new ones.

The normal gap on Niva spark plugs is 1.1-1.2 mm.

Which Spark Plugs are Best for Chevrolet Niva

Several general questions that Papuan services either “forget” or never knew about. The tightening torque must correspond to that specified by the manufacturer. The metal sealing ring should not turn into foil when tightened, otherwise it will cease to perform its function. It is advisable to install the spark plug with copper, aluminum or ceramic lubricant, especially in our case when we have an aluminum cylinder head.

There is no need to pour lubricant as much as you can; one drop on the threaded part is enough so that next time the spark plug does not “stick” and can be easily unscrewed. Now about gasoline and spark plug life. Don’t think that if you installed a new set, you will run on the spark plugs until they die naturally. ONE “left” filling is enough so that a set of candles can be thrown into the trash.

The topic of this review is Chevrolet Niva and Niva spark plugs, using the example of the German manufacturer Bosch. There are similar lines from other manufacturers, but since I am currently working with this manufacturer, I will tell you using the example of its products.

spark plugs for the Niva family

1. Spark plugs for carburetor cars. The factory gap between the electrodes is 0.7 mm. I will not describe all the marketing gimmicks that the manufacturer writes, just high-quality spark plugs that maintain their required engine hours. Frequently asked question: the contact ignition system has been replaced. A distributor with a hall sensor, a switch and a coil from 2108 are installed. What spark plugs should I use? I experimented with this issue several times. I decided for myself: regular carburetor spark plugs with a slightly increased gap, literally by 0.1-0.2 mm. Produced in Germany.
2. Spark plugs recommended by the manufacturer for 8 valve injectors, including for the Niva-Shniva family. The established gap between the electrodes is 1.1 mm. In the case of these candles, it would be fairer to say “workhorse”. Nothing outstanding, but they work until either diesel fuel is poured into the tank, or the gap increases to 1.5 mm. Bosch located the production of these candles in Russia, which, unlike other manufacturers, had a very positive effect on the price.
3. A spark plug with a central electrode coated with platinum. Named . I’ll dispel the common myth that you install “platinum” or “iridium” spark plugs and the horn will fly like an airplane. The main advantage of these candles is their RESOURCE. When you install ordinary spark plugs, after 10-15 thousand the gap between the electrodes “goes away” due to the “knocking out” of the central electrode by a spark. According to my observations, with good gasoline, “platinum” spark plugs, without deteriorating their parameters, have a resource of more than 50 thousand km. Produced in Germany.
4. Multi-contact spark plugs. In this case, four-pin. For a long time I could not clearly explain to clients what the “raisin” of the issue was. I will not repeat the nonsense that is said in stores and markets. The answer came when a batch of candles was sent to Yakutsk, to the same “junior-experimenter” like myself. It was a completely different SUV, but then this was confirmed in our cars. Their main advantage is starting the engine in the morning in very cold conditions. This has led to some of my clients installing "seasonal" candles on their cars. In summer they are ordinary, in winter they are multi-contact. Candles are made in Germany.

Inspecting the spark plugs helps you find any engine problems without calling a special service center. Particular attention should be paid to the appearance and color of soot. The usual condition of a spark plug that does not require replacement is moderate burnout of the electrode, a complete absence of oil stains, and an additional small amount of soot and coffee-golden deposits on the insulator.

Chevrolet Niva is a popular Russian jeep. Car owners appreciate it for its good cross-country ability and excellent appearance. Among the advantages of the Chevy Niva, its owners note fast heating and good ventilation, small size and good interior, good-quality optics and cheap service.

When operating in Russian conditions, it is important that the engine can be started in cold weather. In the Niva Chevrolet car, what remains to be done for our client is ok. The spark plugs are also in good working order, otherwise the engine power will decrease.

The Russian proverb “prepare a sleigh in summer and a cart in winter” is best suited here. It is better to check that this is necessary and replace the spark plugs immediately after the car switches to summer operation. If your Chevrolet Niva did not travel long distances in winter, the spark plugs might be late in warming up to the self-cleaning temperature, which means they became covered with carbon deposits on the tips.

The low quality of the fuel also has a bad effect on the spark plugs - they are the first to take the blow personally and there are variations even when they fail. If the spark plugs are oily, filled with fuel, coked with carbon deposits, or have an incorrect gap between the electrodes, they need to be cleaned, the gap adjusted, or replaced.

VAZ-2123 injection engines have been produced for more than 10 years, and during this time they have been brought to the Euro-4 standard. AvtoVAZ supplies these engines with A17DVRM spark plugs supplied from the city of Engels.

Chevrolet Niva is a popular Russian SUV. Car enthusiasts appreciate it for its excellent cross-country ability, as well as its beautiful appearance. Among the advantages of the Chevy Niva, its owners note fast heating and good ventilation, compact size and comfortable interior, high-quality optics and inexpensive maintenance.

When operating in Russian conditions, it is important that the engine can be started in cold weather. The Niva Chevrolet car has everything in order with this. The spark plugs must also be in good working order, otherwise the engine power will decrease.

In this case, the Russian proverb “prepare a sleigh in summer and a cart in winter” fits perfectly. It is better to check and, if necessary, replace the spark plugs immediately after the car switches to summer operation. If your Chevrolet Niva did not travel long distances in winter, the spark plugs may not have had time to warm up to the self-cleaning temperature, which means they became covered with soot on the tips.

Low quality fuel also negatively affects the performance of spark plugs - they are the first to take the blow and may even fail. If the spark plugs are oily, filled with fuel, coked with carbon deposits, or have an incorrect gap between the electrodes, they must be cleaned, the gap adjusted, or replaced.

Recently, the automotive market has been replete with different spark plug options. Moreover, many are so advertised that an inexperienced car enthusiast can easily get confused. This article will highlight Chevrolet Niva spark plugs - popular product options, as well as recommendations for replacement and selection.

If the appearance is unsatisfactory, then they need to be replaced. To purchase this copy, a car enthusiast will have to fork out a lot, considering the cost of other options. As a result, engine power weakens and fuel consumption doubles.

If your Chevrolet Niva did not travel long distances in winter, the spark plugs may not have had time to warm up

As a result, the Niva Chevrolet spark plugs do not warm up enough to clean themselves. The higher the value, the colder the product. But this figure can vary greatly depending on the type of fuel used.

The only drawback of high-quality candles may be their cost. And of course, high-quality parts for your Chevrolet Niva cannot be cheap.

If it overheats, it will not last long. Size plays an important role, that much is clear.

If its size is small, the part simply will not screw into the socket and then the electrodes will be at a great distance from the combustion chamber. If the length is longer than necessary, then the electrodes will stick out, and this increases the risk of contact with the piston.

If on the central electrode and its skirt you find a dense layer of oil with particles of cylinder destruction and drops of unburnt fuel, it means that one of the valves is damaged or the partition between the piston rings is broken.

In addition, knowing the exact size, you can choose the best heat rating (video author - VanLe9).

All products from the DENSO IRIDIUM POWER series have proven themselves well. For the “2123” motor, one option is suitable, IW20, but IK20 is already a turnkey “16”. The cost of the kit can exceed 90 euros. Do we need it?

On the left is a BOSCH SUPER 4 spark plug.

Those who bought spark plugs with four electrodes are happy. We are talking about the BOSCH SUPER 4 series and the WR78X version. But here, again, you will have to overpay. And that’s why they often choose NGK products. We are talking about the V-line line and option number 13. We need V-line 13 BPR6ES-11 spark plugs. Their service life in the “2123” engine can reach up to 60 thousand.

The modern automotive market offers a huge number of options for spare parts and consumables. Not every experienced motorist is able to immediately understand which spark plugs are best for the Niva Chevrolet. In order not to make a mistake with your choice, it is recommended to familiarize yourself with the advice of experts.

Niva's original spark plugs

The Niva is supplied from the factory with domestic spark plugs from the Engel plant, which specializes in the production of automotive spark plugs. The plant installs AU17DVRM brand spark plugs; these plugs have proven themselves well and meet all quality standards and service life.

A large number of analogues of these spark plugs have appeared on the market, which are no worse than factory ones, and sometimes even better. Analogues of candles can be both imported and domestic.

Below is a table of spark plugs suitable for a Niva car from well-known brands such as DENSO, BOSCH and Brisk.

Expert recommendations

Niva Chevrolet injector with VAZ-2123 engine are equipped with A17DVRM spark plugs. This plant, despite the fact that it is located in Russia, belongs to Bosch. These German manufacturers have proven themselves well in the market.

It is important to consider some differences when choosing a SZ:

• EZ A17DVRM consists of Russian-made parts;
• APS A17DVRM consist of German-made parts.

To avoid confusion, you should always look closely at the markings. Speaking about the second option, one must also take into account the fact that APS A17DVRM are manufactured using advanced technologies. Among other things, they are distinguished by better processing of the electrodes, and therefore you can avoid problems with a running spark, which is typical for defective devices.

When choosing suitable products, you need to follow some rules:

1. DENSO IW20 and NGK devices contain a sufficient amount of iridium, which has a beneficial effect on engine life.
2. BOSCH WR78X parts accommodate four electrodes.
3. GM WR8DCX are suitable for use in winter and summer. They are preferable to the aforementioned A17.

The best candles for Niva

Based on reviews from forums, it has been repeatedly revealed that Nivovody gives their preference to NGK candles. These spark plugs are excellent for the Niva engine and can withstand high temperature loads. NGK spark plugs make it easier to start the engine in cold weather and even reduce fuel consumption due to their structure. The closest to standard spark plugs and suitable in design to the Niva engine will be NGK No. 11 spark plugs.

These spark plugs easily overcome the 30,000 km barrier without any damage.

The best manufacturers for Chevrolet Niva

If you are about to replace the spark plugs, then you need to know what to put on the injector of your car. Among all the options currently presented on the automotive market, the leader for the Chevrolet Niva can be considered the Bosch Platinum WR7DPX products, which have a gap of 1.1 mm.

Due to the fact that they are popular, fakes are very common. When installing low-quality spark plugs on a car, its engine will begin to perform noticeably worse, fuel consumption will increase, and problems with the operation of the power unit will begin to appear. It is better to initially purchase high-quality original parts, since over time it will be quite problematic to detect a fake.

The Japanese DENSO W20TT are also very popular. They have numerous advantages:

• excellent quality;
• presence of a powerful spark;
• stable engine start.

Another great option is NGK spare parts. The main feature of this and the previous version is that they are iridium. The advantage of using them is a longer service life. They do not need to be replaced for 100 thousand kilometers. Also, when installing iridium analogues, the rated power of the power unit increases and the acceleration dynamics increase.

Of course, if spark plugs provide benefits on one engine, they may have a negative effect on another. That is why it is important to select them taking into account the characteristics of a particular vehicle and the recommendations of the vehicle’s operating manual.

The service life of conventional spark plugs ranges from 20 to 30 thousand kilometers. It is very important to replace them regularly and not drive them for more than the allotted time. Otherwise, this may result in negative consequences for the system - lead to failure of high-voltage wires and the ignition coil.

NGK spark plugs

You can find out which spark plugs are better for a Chevrolet Niva using the list below. Speaking about the best manufacturers, we need to mention BOSCH PLATINUM WR7DPX spark plugs with a gap of 1.1 mm. Due to their popularity, they are copied, so you can find many fakes on the market. If you install such an option in a car, engine performance will noticeably decrease and problems will begin. The catch is that the symptoms do not appear immediately, so identifying a fake is not so easy.

Japanese-made DENSO W20TT devices can be considered popular. They have many advantages, which include good quality, a powerful spark, and therefore reliable engine starting. We can say that they do not have any drawbacks, except for one, but quite significant one - the price. To purchase this copy, a car enthusiast will have to fork out a lot, considering the cost of other options. The fact that there is a sea of ​​fakes on the automobile market, perhaps, need not be mentioned.

There is another great option - NGK spark plugs. These spark plugs for Niva Chevrolet injector, like the previous ones, are iridium. The key to the success of iridium SZs is that when purchasing them, you can get rid of thoughts about problems with them for a long time. To install iridium and platinum products, unfortunately, you will have to disassemble half of the engine. In return, they reduce acceleration time and increase the rated power of the engine.

So, to summarize, what is good for one engine may be bad for another.

A little about the manufacturers. I can name several companies that produce spark plugs for Chevrolet Niva and Niva. These are Champion, Eyquem, Beru, Denso, Valeo, NGK. A few words about NGK. I used the products of this manufacturer for a long time until “small” problems began. A new set of spark plugs was installed on the car, and after a couple of thousand, one spark plug would “fly out” and the engines would start to stall.

So I bring candles not only for myself, but also for several diagnostic companies, statistics have appeared, this phenomenon has become common. Without being lazy, I sent several sets to the Moscow representative office. They diplomatically answered me: I’m a fool, the candles are tightened with the wrong tightening torque. Well, they sent it nicely)) Having waited until NGK held a seminar in Russia, I went and laid out everything to the “real Japanese”.

Having made a thousand Japanese apologies, in a private conversation, he said that for the sake of competitive prices, the production of the cheap segment of candles was transferred to other factories. But the percentage of defects is within normal limits and sellers and services need not worry. And if something happens, then send the defect to the representative office for examination. The circle is closed. Since 2011, I began working with products from German manufacturers Bosch and Beru.
