20 best spark plugs

Prices on the market are constantly rising, and what you used before may not be affordable today. In search of worthy analogues of spark plugs, be sure to pay attention to Finval products. These are the best candles in their segment, and even at the most attractive price. One module costs only 170 rubles, and this is when the cost of Denso or NGK can reach a thousand. From the technical side, candles are also interesting. According to the test results, it became clear that they do not grab stars from the sky, but they fully comply with the stated requirements and without problems run back the 30-40 thousand kilometers they are supposed to. It does not matter which engine you put them in, an old VAZ or Hyundai.

Two-electrode spark plugs from a Japanese manufacturer are one of the most successful options for completing the engines of the Nissan B auto platform (LADA, Nissan, Chevrolet, Renault). No "jambs" in the work. It is the high quality of manufacture that ensures the duration of operation (up to 40 thousand kilometers - the resource is highly dependent on fuel) and the stability of the spark supply. The traditional and less expensive nickel coating of the electrodes gives the latter resistance to the combined effects of negative factors (carbon deposits, high temperatures and general aggressive environment). Fuel consumption is not much different from that when using regular branded candles.

An interesting version of spark plugs from a German manufacturer, which gives a maximum increase in fuel economy compared to single-electrode analogues. Possessing, in general, a standard structure inherent in almost all candles from Bosch, the W7 DTC Standard Super presents some very pleasant “surprises” revealed during complex tests. The greatest success of the Bosch W7 DTC Standard Super has been achieved in the flow component. A decrease of 3.2% is an excellent result, especially for engines that are far from the first freshness.These candles are well bought up by the owners of LADA, Chevrolet and VAG-group cars.

A very good candle of the V-Line series, which has a V-shaped recess on the central and a slight rounding on the two side electrodes. It has the best detonation time and efficient ignition of the mixture, which, in turn, causes a slight forcing of the engine. Among other things, NGK BKR6EK provides more complete combustion of fuel, thereby positively affecting the overall efficiency of the engine. The main irony of these candles lies in the fact that, made in Japan, they are not used in Japanese cars. Most often, these kits can be found in cars of the brand "LADA", "Audi", "BMW" and "Skoda", which clearly demonstrates the company's focus on the European segment.

A candle with a high degree of reliability, very popular in Russia (used in VAZ, Audi, Chevrolet, Mercedes, etc.). The basis for the success of Bosch FR7LDC + is a non-trivial approach to the manufacture of the electrode part. The main nuance lies entirely in the variety of materials used. The central nickel electrode of the spark plug is alloyed with yttrium, a rare earth metal that significantly increases the stability of the work. This combination protects the metal from corrosion and ensures efficient heat dissipation. As a result, we get a reliable and efficient candle, the resource of which is enough for 50-60 thousand kilometers.

The eminent Swedish company Husqvarna has been producing spark plugs for a long time, and most often they are designed for garden equipment. But now we have a model suitable for use in car engines, and this is a rather rare occurrence in the brand's catalog. In terms of indicators, it is difficult to single out any unique qualities. Plain, classic candle with a copper core and one non-codified side electrode. That's just the gap here is non-standard, so experts do not recommend using this product in injection engines or those that run on gas fuel. Otherwise, there are no restrictions, however, as well as recommendations.

Three-electrode candle Champion N9BYC4 - the sole leader in reducing fuel consumption, as well as increasing power when throttling the engine (on average by 5-5.6%) relative to single-electrode candles. In addition, there is a noticeable improvement in the stability of work, even despite the mediocre results of the check in the pressure chamber. In general, there is nothing to highlight from the geometric features of the electrode part - against the background of various grooves, grooves and other constructs from other manufacturers, this candle looks canonical.Champion N9BYC4 is successfully used in all running cars in Russia.

A spark plug with an asymmetric ground electrode arrangement: two of the four are 0.8 mm from the stem, the others are 1.2 mm apart. This is done specifically to maintain a spark under all operating conditions and bypass potentially unfavorable situations that arise, such as severe "smoking" of insulators. In other words, such a problem as the quality of gasoline does not in the least affect the performance of a candle, the resource of which is enough for 60 thousand kilometers (if not a fake). An additional "bonus" Beru Ultra-X 79 is the compatibility with engines on gas equipment, where the greatest efficiency is noted.

If you have Lada, Renault or Hyundai, you most likely have never heard of this brand. It is quite rare in Russian stores, as it produces candles specifically for American cars. It is a premium brand owned by General Motors. Here they don’t really bother about the price, so there are not so many fans of candles. But the quality is at the highest level. According to the manufacturer, these candles are designed for 160 thousand mileage, and this is an absolute record that even the best brands from Europe or Asia cannot boast of. There is no reason not to trust these assurances, but you can’t find real tests on the network, and this could significantly justify the price tag.

The best spark plugs are not only produced by Japanese brands. We now have a prime example of this. This is also a popular manufacturer, and in this case, he surpassed his Asian competitors in all respects. It uses a copper core with a zinc coating. There are 3 side electrodes, and all of them are nickel-plated. The candle has increased thermal conductivity, and as a result, an increased resource.According to the documentation, the module is designed for 70 thousand mileage, which is twice as much as that of competitors. They can be installed in both injection and carburetor engines, and among the recommending concerns there are not only VAZ Lada, but also Renault and Mercedes. True, all cars of past generations.

Iridium spark plugs are the best because they are versatile. They can be installed in injection and carburetor engines. They fit both VAZ and Hyundai or even Mercedes. They have no restrictions at all, but an increased resource. But Bosch wouldn't be one of the market leaders if it didn't go further. Before us are not just iridium candles, but double ones.That is, double deposition is used here, although the central electrode is rather thick, which is uncharacteristic for this segment. As the manufacturer assures us, these candles run about 80 thousand kilometers, but we cannot confirm or deny this fact. The model is relatively new and there are no independent test results online yet.

The Finnish brand Finval is famous for its adequate prices, and it does not matter in which segment its products are located. Now we have iridium candles, which are recommended to be installed in new VAZ Lada models, as well as in Renault and a number of Hyundai models. Candles of the budget segment for budget cars, but with top parameters and an extended service life. The guaranteed mileage is more than 40 thousand kilometers, which is slightly higher than that of analogues with a copper or nickel electrode. Yes, the indicator is not top, but honest, as it is confirmed by independent tests. In addition, the brand has serious copy protection, so it is almost impossible to run into a fake.

Iridium spark plugs are among the most expensive on the market. Yes, they are the best in most indicators, but their resource often does not differ from cheaper nickel or copper models. But you can always find an option that differs from the total mass in its characteristics. This candle is just that. Firstly, it has an increased resource: according to the manufacturer, 100 thousand kilometers. Tests slightly reduce this figure, but it is still impressive. Secondly, there is the most attractive price tag here: 900 rubles for a top brand and its segment is very cheap. The main thing is not to run into a fake, of which there are a lot on the market due to the popularity of the model among buyers.

A candle that has not lost its relevance in large consumer masses. It has a thin central electrode (0.4 mm), due to which it does not live long, but it allows you to significantly save fuel and burn the mixture in the combustion chamber as much as possible.The main influx of power here (equal to 2-3%) is involved in increasing the efficiency of the engine by reducing misfires and the rhythm of the spark supply. Despite the short life, the resource of the iridium tip cannot be called low: it reliably works out up to 30 thousand mileage, and, depending on the methods of operating the vehicle, is able to work beyond the appointed time.

Iridium spark plug with long working life. According to numerous users, one set is enough for an average of 50 thousand kilometers, however, when using high-quality high-octane fuel, this figure can increase to 60-65 thousand kilometers. In terms of fuel economy, there is no particular difference with inexpensive candles, however, the economic factor is expressed by working out the entire period of the declared operation. The cost is high, due to the iridium coating applied to the central and only side electrode.

In most cases, platinum, silver or iridium spark plugs contain these materials only as solder to the center electrode. While the mass remains simply nickel-plated. But some manufacturers go further and spray on the side module as well. This is what the Japanese manufacturer MASUMA did, which is not very popular in the Russian and European markets, but is well known in Asian countries. It is these candles that are put on some models of Hyundai and Great Wall. But they are also recommended for Skoda, Audi and Renault. Double spraying affects stability and corrosion protection. Candles perfectly cope with harsh conditions and steadily run through the designated resource of 40 thousand.

Top brands are very often faked, and often it is almost impossible to distinguish a copy from the original.But some brands pay very close attention to this issue, for example, like Champion. When buying these spark plugs, you can be 100% sure that you are buying the original. Protection is present both on the packaging and on the body of the candle itself in the form of complex embossing with the logo and brand name. As for the technical side, these are quite classic platinum-coated candles that will fit in any engine: it doesn’t matter if you have a Lada or a Mercedes. The list of recommendations from concerns is very extensive and even includes premium brands, which tells us about the quality of performance.

Laser Platinum is a relatively new line of the NGK brand. These are the most technologically advanced candles with top characteristics. For example, here we see a thick platinum soldering, which significantly increases the working life - up to 60 thousand instead of the classic 30 thousand kilometers. At the same time, throughout the entire period of operation, the model shows the same efficiency. The spark remains stable even though there is only one ground electrode. But it is modified, with a modified geometry and a recess in the center. In general, top quality, but the price is appropriate. These are some of the most expensive candles on the market today, and even their long life does not offset the price tag.

It is believed that silver spark plugs are mainly put in a premium car engine, as they are quite expensive. But there are exceptions, one of which is now before us. This is the cheapest silver-coated candle, and on both electrodes at once. There are no unique features here. A classic at its best, but it is the combination of all factors that makes it the most popular among owners of inexpensive cars from VAZ, Renault or Hyundai. Moreover, the candle is praised by both the owners of injection and carburetor engines. The resource is standard, about 30 thousand km. The manufacturer does not deceive buyers, therefore, he honestly declares about him, without embellishing.

Very common candles among owners of cars of the Nissan B platform (Renault, Nissan, VAZ).They liked it for a high indicator of a working resource (about 40 thousand kilometers on fuel of not the highest class) and for the corresponding low cost. In terms of quality, Denso PK20PR-P8 is also all right: Japanese manufacturers, as they say, did a great job on platinum coating and electrode geometry. The only problem during operation can be a small interelectrode gap, made so for the sake of sparking even at low mains voltage. Nevertheless, motorists are not at all embarrassed to purchase these candles.
