9 best spark plugs

Car manufacturers do not produce consumables. This also applies to spark plugs. Moreover, the candles with the logo of your car are actually produced at third-party enterprises, with which the auto concern has a contract. The cost of such products, as a rule, is too high, the buyer pays extra for the name. Does this mean that you can buy the same candles, produced under the brand name of the manufacturer, but without an extra charge of automaker? Of course, yes! We will help motorists save money when buying consumables. For the same money, you can buy both premium products and candles with mediocre characteristics, bearing a big name.

Spark plug which company to choose

There are several varieties of candles. Two or more electrodes, flare design, plasma flare ignition. All manufacturers have in their range of spark plugs with different types of electrodes.

Your attention the best of them:

1. BOSCH

2. Ngk

3. CHAMPION

4. BRISK

5. DENSO

The choice of the manufacturer is not as fundamental as the choice of model and manufacturing technology.

Nevertheless, some features of the brands can be distinguished:

• Bosch has an OEM contract for Mitsubishi, Fiat, Audi, Peugeot, Toyota.
• NGK cooperates with such automakers as Ferrari, Ford, Volkswagen, Volvo, BMW.
• Champion is commissioned by Suzuki, GM, Jaguar, Volvo, Alfa Romeo.
• Brisk produces candles with the Audi, Opel, Skoda and BMW logo.

Accordingly, buying a spark plug with the logo of the manufacturer’s company that manufactures products for the brand of your car, you simply save money without losing quality. Often the part number of the product coincides with the brand of the car and the original name of the manufacturer.

The best spark plugs with two electrodes

Denso PK20PR-P8

Candles of this series have a platinum coating on the electrodes. Despite the simple design (only one side electrode), the quality of sparking is not inferior to multielectrode structures.

Manufacturers managed to get the durability of the iridium candle using a cheaper metal - platinum.

Benefits:

• The cost of such a candle is not much higher than that of products without the use of precious metals.
• The resource significantly exceeds the replacement time established by the maintenance regulations.
• It has modifications for most models of cars, including discontinued.
• The candle cleans itself well at high speeds.
• High quality threaded connection.
• Reliable sealing ring.

Disadvantages:

• Regular clearance does not always meet the specifications of the automaker, you have to set it before replacing.
• Does not like long work at idle, is covered with soot.
• Poorly compatible with liquefied gas.

NGK BKR6EIX

One of the best examples of duration of use. Motorists note in the reviews that this candle does not lose performance up to a run of 50,000 km. Iridium coating, hence the highest cost in the review.

Significant savings in comparison with cheap candles will not work. The cost is more expensive just as much as the kit lasts longer. However, all this time you will be confident not only in a stable engine start, but also in the normal consumption of gasoline.

Benefits:

• The resource from replacement to replacement surpasses many analogues.
• The electrode does not burn out when the gap is reduced, the candle works confidently with a weakly charged battery.
• Ideal for installation on a relatively new engine, during the corresponding MOT.
• The high-strength center electrode insulator does not form cracks even with solid runs.

Disadvantages:

• Sensitive to fuel quality. A pair of gasoline refills with an excess of additives and the kit fails.
• High price does not guarantee savings on the resource.

Bosch WR7DP

This candle has an innovative design of the central electrode. The thinnest core is flush mounted in a ceramic insulator. As a result, the spark becomes similar to a plasma discharge that stably operates at a reduced voltage in the on-board network.

Platinum coating allows you to increase the resource between replacements up to 60,000 km, but only when using high-quality fuel. The price is high, but it is far from iridium analogs.

Benefits:

• The original design of the central electrode protects platinum plating.
• Stable start at reduced voltage.
• The shape of the spark resembles a plasma-flare system.
• Good central contact coverage.
• With a fully open throttle, this spark plug provides an increase in power of up to 5% without increasing fuel consumption.
• This series has modifications for most car models, including domestic ones.
• High environmental performance exhaust.

Disadvantages:

• High price. However, this is justified by the quality.
• Lack of fuel economy compared with regular candles.

Champion RN9YCC4

A distinctive feature of the design is the copper core at both electrodes: central and lateral. On the one hand, current losses at low voltage are reduced, on the other hand, not the highest resource. At the same time, the price is at the level of the top models. A positive moment is a good increase in power, especially at high speeds, when cheaper counterparts produce an unstable spark.

Benefits:

• Good economy at medium and high speeds.
• Holds the load - with a sharp opening of the flap works without failures.
• Excellent environmental friendliness - without fear of being tested for CO.

Disadvantages:

• Too high price, even for outstanding performance.
• At low revs the spark may be unstable.
• Not suitable for all car brands (factory specifications).

Best multi-electrode spark plugs

Denso K20TXR

These candles are a vivid example of how to save money without overpaying for the automaker logo. In terms of characteristics, design, and appearance, they are no different from models produced by the order of automakers. You can safely buy instead of the original - except for saving money, no difference.

The model belongs to the budget class - nickel plating. However, several side electrodes provide steady sparking.

Benefits:

• Top quality workmanship, no defects in production.
• Reasonable cost, lower than platinum. At the same time there are no differences in quality.
• Good protection against spark erosion.
• High corrosion resistance, still nickel coating.
• Wide slots on the nut.
• As for candles without the use of precious metals - a high resource.

Disadvantages:

• Inconvenient to adjust the gap - too strong side electrodes.
• On liquefied gas results are mediocre.

Bosch FR7LDC +

Economy class in the line of multi-electrode candles. The cost is significantly lower than the original, while the characteristics are practically the same. Yttrium coating. Not platinum of course, but the resource increases.

When poor quality fuel gets into the cylinders, the characteristics deteriorate, the economy class costs.

Benefits:

• Excellent price, while the resource is not much less than the original.
• When working with high-quality fuel, good performance indicators.
• Yttrium coating ensures high resistance to spark erosion.

Disadvantages:

• Characteristics are highly dependent on fuel quality. Not suitable for use away from proven network gas stations.
• Due to the high popularity of the model, there are many counterfeit items on the market. Differ from the present is quite difficult.

NGK BUR6ET

The candle is not cheap, but the difference in cost with the original is offset by outstanding properties. Nickel electrode coating that guarantees corrosion resistance. Most consumers say sustainable work in any range of revolutions. This is also confirmed by professional tests. Candles of this model are always in the top three.

Benefits:

• Three side electrodes guarantee sparking under all conditions.
• Not bad carry low-quality fuel.
• Good economy, especially under load.
• The increase in power in comparison with regular candles is more than 4%.
• The resource exceeds the interservice replacement time twice.

Disadvantages:

• High price. For nickel coating a bit too much.
• Exhaust toxicity is not the most outstanding.

Brisk Premium LOR15LGS

The original design of the electrode module. Four side electrodes are located below the cut of the central rod. As a result, sparks entangle the central electrode from the insulator to the cut to the web. The reliability of ignition increases, the density of the spark is 360⁰.

This is a patented system, almost no analogues. Due to the dense spark, ignition occurs at the very initial phase of the fuel supply. Profitability at a high level. Unfortunately, high technology costs a lot of money - this is one of the most expensive candles on the market.

Beru Ultra-X 79

Economical price combined with excellent consumer properties. This candle has contradictory indicators: the manufacturer in the technical characteristics indicates incompatibility of work with LPG, and users, on the contrary, note the high quality of work on natural gas.

The candle has four electrodes, differently distant from the core. Two electrodes have a gap of 0.8 mm, the rest - 1.2 mm. As a result, an equally stable spark is formed under different operating conditions, even with a highly sooty insulator. It turns out imitation of the surface discharge in the traditional version.

Benefits:

• The highest profitability among multi-electrode structures.
• Low exhaust emissions.
• Reliable spark when heavily contaminated electrodes.
• Users have noted a decrease in engine running noise.
• Stable work on liquefied gas.
