Best spark plugs for buyers' reviews

Manufacturers of cars 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 car dealership has a contract. The cost of such products, as a rule, is overstated, 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 the premium of the carmaker? Of course, yes! We will help car enthusiasts save money when buying consumables. For the same money you can buy both premium products, and candles with mediocre characteristics, bearing a big name. Get more information, and save money. At your service, customer feedback and opinion of auto experts.

Which spark plug to choose

There are several types of candles. Two or more electrodes, a torch structure, plasma torch ignition. All manufacturers have in their assortment spark plugs with different type of electrodes.

The best of them:

1. BOSCH

2. NGK

3. CHAMPION

4. BRISK

5. DENSO

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

Nevertheless, we can highlight some of the features of the brands:

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

Accordingly, having bought a spark plug with the logo of the manufacturer of the manufacturer that produces products for the brand of your car, you will simply save money without losing quality. Often the part number of the product coincides on the consumables with the brand of the car and the original name of the manufacturer.

The best spark plugs with two electrodes

Denso PK20PR-P8

The candles of this series have platinum coating on the electrodes. Despite the simple design( only one side electrode), the quality of sparking is not inferior to multi-electrode constructions.

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

Advantages:

• 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 deadlines set by the maintenance schedule.
• Has modifications for most models of cars, including those removed from production.
• The spark plug is self-cleaning at high revs.
• High quality threaded connection.
• Reliable sealing ring.

Disadvantages:

• The nominal clearance does not always correspond to the specifications of the automaker, it is necessary to expose it before replacement.
• Does not like continuous work at idle, it is covered with carbon.
• Poorly compatible with liquefied gas.

NGK BKR6EIX

One of the best copies for the duration of use. Motorists note in the reviews that this candle does not lose its characteristics up to a run of 50,000 km. The coverage is iridium, hence the highest in the review cost.

Significant savings compared to cheap candles will not work. The cost is more expensive exactly as long as the kit goes for longer. However, all this time you will be sure not only of a stable start of the engine, but also of the normal consumption of gasoline.

Advantages:

• 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 mounting on a relatively new motor, during the corresponding maintenance.
• The insulator of the central electrode of increased strength, even with solid runs, does not form cracks.

Disadvantages:

• Sensitive to fuel quality. A couple of gasoline refills with an excessive number of additives and the kit breaks down.
• The high price does not guarantee a saving on the resource.

Bosch WR7DP

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

Platinum coating allows increasing the service life between replacements up to 60,000 km, but only with the use of high-quality fuel. The price is high, but far from iridium analogues.

Advantages:

• The original design of the central electrode protects platinum spraying.
• Stable starting with low voltage.
• The shape of the spark resembles a plasma-flare system.
• Good cover of the central contact.
• With the throttle fully open, this candle provides a power boost of up to 5% without increasing fuel consumption.
• This series has modifications for most car models, including domestic ones.
• High environmental performance.

Disadvantages:

• High cost. However, this is justified by quality.
• No fuel economy compared to standard candles.

Champion RN9YCC4

Distinctive feature of the construction - 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 price at the level of the top models. A positive moment is a good increase in power, especially at high revs, when cheaper analogs give an unstable spark.

Advantages:

• Good economy at medium and high revs.
• Keeps the load - with a sudden opening the damper works without fail.
• Excellent environmental friendliness - you can pass the test for CO without fear.

Disadvantages:

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

Best spark plugs with multiple electrodes

Denso K20TXR

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

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

Advantages:

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

Disadvantages:

• It is inconvenient to adjust the gap - too strong side electrodes.
• The results are mediocre on liquefied gas.

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. The coating is yttrium. Not platinum of course, but the resource increases.

If you get into the cylinders of poor-quality fuel, the characteristics worsen, the costs of the economy class.

Advantages:

• Excellent price, while the resource is not much less than the original.
• When working with high-quality fuel, good economics.
• The yttrium coating guarantees high resistance to spark erosion.

Disadvantages:

• Characteristics are highly dependent on fuel quality. Not suitable for use away from proven network refills.
• Due to the high popularity of the model, there is a lot of counterfeit in the market. To distinguish from the present is quite difficult.

NGK BUR6ET

The candle is not cheap, but the difference in cost with the original is compensated by outstanding properties. The electrode coating is nickel-plated, which guarantees corrosion resistance. Most consumers note stable operation in any speed range. This is also confirmed by professional tests. The candles of this model are always in the top three.

Advantages:

• Three side electrodes guarantee sparking under all conditions.
• Not bad carry a fuel of poor quality.
• Good economy, especially under load.
• The addition to capacity in comparison with standard candles is more than 4%.
• The resource exceeds the service interval of replacement twice.

Disadvantages:

• High cost. For a nickel coating a bit too much.
• Toxicity of exhaust is not the most outstanding.

Brisk Premium LOR15LGS

The original design of the electrode module. The four side electrodes are below the center rod. As a result, sparks entangle the central electrode from the insulator to the sheath. The reliability of ignition increases, the density of the spark 360⁰.

This is a patented system, there are practically no analogues. Thanks to a dense spark, the ignition occurs at the very first phase of the fuel supply. Economy at a high level. Unfortunately, high technologies cost a lot of money - this is one of the most expensive candles on the market.
