In order for the fuel-air mixture of the engine to ignite perfectly, a stable ignition spark is needed at the right moment. Therefore, choosing the right spark plug is essential for optimal combustion and performance development of the engine. Especially with the heat value, attention should be paid to the manufacturer's specifications. Since each manufacturer presents the heat value differently, for example, a Bosch heat value of 3 can correspond to an NGK value of 9. For reference, each vehicle manual lists the manufacturer's specifications along with alternative spark plugs and their exact designations or type codes.

We work with the official vehicle application lists from manufacturers and offer you the exact spark plug suitable for your vehicle.

Care should be taken when using suppressed spark plug connectors; double is not necessarily better in this case, and a suppressed spark plug should not be used because the overall suppression resistance would be too high.

• High-quality aluminum oxide silicate ceramic creates a stronger insulator for optimal performance
• 98% pure copper core offers excellent heat dissipation and conductivity
• Cold-rolled thread prevents cross-threading and damage to the cylinder head
• Outstanding material coating provides excellent corrosion protection

NGK high-performance racing spark plugs are specially developed for motorsport and ideal for performance engines with permanently high RPMs. Unlike standard plugs, they are particularly resistant to vibrations, heat loads, and high speeds. Perfect for trouble-free and performance-enhancing performance under demanding racing conditions. Therefore, this type of spark plug is not recommended for normal road traffic.
