10 best spark plug manufacturers

Spark plugs are a very important structural element of an internal combustion engine, whose work is based on an electrical breakdown between two contacts (electrodes). As a result of the arc burning, the compressed air-fuel mixture supplied to the engine's combustion chamber ignites and, creating pressure, pushes the piston in the opposite direction. As a result of this action, the chemical energy of the fuel is converted into a mechanical motion of the crankshaft.

It becomes clear that without an important phase of ignition of the fuel, there would be no talk of any internal combustion engine. In this regard, the most stringent technical requirements are imposed on the spark plug, aimed at ensuring uninterrupted spark supply, a high degree of durability, as well as the efficiency of burning the supplied fuel volume. It is noteworthy that at present more than five dozen large companies around the world are engaged in developing candles, but far from everyone has earned the honorary title of a “national” producer. After conducting a thorough analysis of the market, we have compiled for you a rating of the best manufacturers of spark plugs, whose popularity has been confirmed by thousands of satisfied consumers and dozens of reputable experts.

Top 10 best manufacturers of spark plugs

10 Valeo

The French brand has a large sphere of influence in the European market, but we are better known as a supplier of spark plugs for the replacement of Czech models of Brisk. Indeed, in terms of working moments, the range of companies listed has a lot in common, ranging from a similar working resource to consumption efficiency indicators. However, there is one negative nuance seen when the engine is running on Valeo candles: the stability of work suffers because of the presence of gaps (especially at low voltage).

As an example of Valeo products, we single out one, but very popular, R76H11 spark plug model, which has the standard parameters for single-electrode plugs. Their small minus: the absence of markings on the preferred engines and interelectrode gap. Advantages: good performance tide of engine power (1.7-2.1%) and fuel economy (up to 2.0%).

9 Finwhale

The first, but not the only representative of Germany in the consolidated rating, the spark plugs of which are of medium popularity in the domestic market. Most consumables from Finwhale love service centers: it is from their filing candles from this company fall under the hood of serviced cars (mainly in the "VAZ", "Hyundai", the old "Fords" and "Mazda").

As consumers note, Finwhale's working resource reserve ranges from 40 to 80 thousand kilometers, and (logically) is highly dependent on the operation of the vehicle.As representatives of the company can distinguish the model F508 and F706, the main advantages of which are low price and lack of fakes, which are often found in more well-known manufacturers. These plugs are purchased mainly for a complete set of LADA engines of brands from 2106 to 21099 and 2110 (16-valve), inclusive.

8 Sct

Another is not the most noticeable in Russia, but a very strong player in the market for spark plugs, sets of which are used as standard consumables from the conveyor. There are four series in the SCT product range, clearly separated by operational rank:

• Classic - candles with a copper core to ensure an effective heat sink, produced both for new cars and for old-style engines (up to the 1969 Chevrolet Camaro and Ford Mustang as well as the popular Plymouths).
• Perfect - candles with increased interval of operation with a tapered insulator tip to ensure a quicker self-cleaning process of the candle.
• Platin - candles with platinum-plated, the resource which in most cases reaches 90 thousand kilometers. It is installed mainly on expensive cars (Porsche, Jaguar, Lexus, etc.), as well as on foreign cars widely used in Russia (Nissan, Honda, Toyota, French Renault and Peugeot ").
• Tuning - a special series of candles, working in extreme conditions. The discharger of these models sits deep into the combustion chamber, providing an increased rate of combustion of the mixture in the initial phase of compression.

7 "Engels Plant"

Perhaps the only worthy representative of the Russian segment of manufacturers of spark plugs, producing strong counterparts of models of foreign production. Their main feature is the low price for the entire range, accompanied by good parameters of quality and duration of use.

One of the brightest representatives of the Standard series, “mixed” on the use of nickel alloy, is the EZ-Standard T17 ADVM 3.0 spark plug with three side electrodes. In terms of efficiency, this model is very close to the Bosch WR7DPX (leader of the test selection of expert tests), considering it is highly environmentally friendly (about 8% of single-electrode samples) and reduced fuel consumption (by an average of 2%). Among the series of yttrium candles "EZ", one can distinguish the WR7DC + model with a 0.8-mm gap and a V-shaped notch on a single side electrode (which increases sparking). The given models perfectly manifest themselves in the domestic cars "LADA" and second-hand foreign cars - "Mercedes", "BMW", "Nissan", "Hyundai", etc.

6 Beru

The German company Beru is another titled representative of Europe, the candles of which are very often placed on domestic LADA (or "VAZ") cars. They are notable for non-standard solutions in terms of the geometry of contact pairs, low (50/50 in assortment) price and long uninterrupted service.

From a huge list of representatives, we give personal preference to the four-contact model Beru ULTRA-X79 with an asymmetric arrangement of paired side electrodes to increase the stability of the spark at normal and low voltage networks. It is not afraid of soot, copes with the ignition of fuel (raising the efficiency of consumption by 1.7%) and is suitable for engines on natural gas. The second example: BERU Z51 with two lateral contacts flush with the end of the central electrode. This candle is distinguished by a small boost of engine power (1.4-1.8%), a reduction in consumption, and is used as an alternative to the base on foreign cars running our country (Chevrolet, Hyundai, Nissan, Renault, and t .d.)

5 Champion

The American giant of manufacture of spark plugs, which has contracts for the supply of products to the conveyor lines "Lexus", "Jaguar", "Alfa Romeo", etc. It has a tendency to constant experimentation with the geometrical parameters of the electrodes, as well as the creation of experimental models for strictly defined operating conditions.

Certainly, Champion's three-touch candle can be called the champion N9BYC4 candle, which, ironically, did not inherit any unique “experimental” features. It is canonical, very durable, and is used on the most popular car brands in Russia: from “LADA” to “Hyundai”, “Chevrolet” and “Renault”. The second “favorite of the audience,” Champion RN9 YCC, has only one side electrode, but can boast the presence of a copper core, which increases its durability (relative to nickel candles) by about 2 times. It is inexpensive and driven around mainly on Asian cars.

4 Denso

Another Japanese manufacturer, under whose office there is the development of four different series of spark plugs:

• Standard. Representatives of this series are made from nickel alloy, without the addition of alloying elements and sputtering. Differs in the presence of a U-shaped groove on the side electrodes, which increases the efficiency of combustion of fuel in the chamber. A striking example is the Denso W20EPR-U.
• Platinum. Wear-resistant candles with platinum-plated on the electrode part and the refined tip of the central electrode. Possess a considerable stock of a working resource and can be used within 60 thousand kilometers of run.
• Irridium. In general, it is very similar to the platinum series (in terms of the structure of the central electrode), however, it is even more wear-resistant due to doping with iridium. An example of such a candle is the Denso Iridium IW20 model, which is widely used in cars with a natural gas engine.
• Twin-Tip. Despite the use of nickel as the electrode material, this series has the highest operational parameters, which is achieved through the use of new technologies.

3 Brisk

The Czech company Brisk is one of the strongest representatives of Europe in this market segment. Distinguished by the presence of seven enlarged series of spark plugs, developed for a particular type of car. The advantage of this production method is that here you can find a candle for absolutely any engine. The disadvantage is that it is very easy to get confused in endless subcategories and models.

Perhaps the Brisk Premium LOR15LGS model candle is the most popular among domestic motorists. The fact is that its design is a rupture of all templates of canonical production, expressed in a significant underestimation and distance of four side contacts with respect to the central electrode. Because of this configuration, the spark at a nominal voltage travels a longer way through the insulator and, as a result, provides a more complete ignition of the fuel mixture in the combustion chamber. A worthy representative of the company, used in cars "VAZ", "Chevrolet", "BMW" and running Koreans ("Hyundai", "Kia").

2 Ngk

In the entire history of its existence, the Japanese company NGK has released a lot of decent spark plugs for gasoline engines. All of them were distinguished by adequate prices, extended service lives (up to 60 thousand kilometers), constant modifications of the geometric visual parameters of the electrode part, as well as reduced fuel consumption rates. However, at the moment, the merit of the company is to create a magnificent (in all senses) candles for engines with gas equipment, covering the needs of 90% of the market.

From the first category of representatives, we give as an example a two-contact NGK BKR6EK candle with a V-shaped groove on the central electrode. Such a solution made it possible to increase the spark burning area, which affected the complete combustion of fuel in the chamber, the flow of power and efficiency.For gas engines, the NGK LPG Line Model No. 2 was invented, which became the focus of technological research. It showed a significant increase in engine power on natural gas (by 3%) and ensured high stability of operation.

1 Bosch

Could not pass by a rating of the best and large German corporation Bosch, which production circle has mentioned also creation of spark plugs for gasoline engines. The use of the standard geometry of the electrode and insulating parts, with small (even dotted) changes in the magnitudes of the gaps, the materials used, including alloying components, became the Germans' signature style. The second proprietary feature affects the cost of products: the vast majority of segment products fall into the budget category.

One of the most popular spark plugs from Bosch in Russia are Bosch FR7LDC + models (two-contact, with yttrium doping of the central electrode and a copper core), as well as Bosch W7 DTC with increased fuel efficiency (reduces gasoline consumption by 3.2% relative to single-electrode models). These candles are often installed on cars "VAZ", as well as foreign brands "Nissan", "Chevrolet", "Toyota", etc.
