Spark plugs play a crucial role in the operation of gasoline engines. Their condition and quality directly affect the stability of the engine's performance and the ease of starting, especially in cold weather. When it comes time to replace spark plugs, the question arises: which ones to choose? We have gathered information on eight of the highest quality and most popular spark plug brands across different price categories to help you make the right choice.

Copper-nickel spark plugs are the most accessible and straightforward to use. However, their electrodes, made from nickel alloy, last no more than 30,000 kilometers before they begin to wear out due to arc erosion.

Platinum spark plugs, thanks to their thin central electrode and slow wear, can last up to 90,000 kilometers, although manufacturers recommend replacing them every 60,000 kilometers.

Iridium spark plugs are the most durable option, lasting between 100,000 and 120,000 kilometers with a properly functioning engine. Their electrodes have high resistance to erosion, but they are also the most expensive. If you are looking for the best spark plugs and price is not a decisive factor, choose iridium or platinum.

Multi-electrode spark plugs were developed to make them more accessible and durable. In such plugs, the spark can jump between different side electrodes, which slows down their wear. As a result, the lifespan of these plugs can increase by 50% compared to two-electrode models.

As for brands, NGK is a name that is known to everyone. Their Yellow Line series is easily recognizable due to its yellow packaging. The V-line series is also popular, featuring a unique shape of the side electrode that ensures reliable ignition of lean mixtures.

If you are looking for spark plugs for a Japanese car, NGK on website ngkparts is a reliable choice. NGK plugs are often used as originals for VAG turbo engines. However, be cautious: due to the popularity of these plugs, they are often counterfeited, and a low price may be a sign of a fake.
