In order for the fuel-air mixture of the engine to ignite perfectly, a stable spark is necessary at the right moment. Therefore, the correct spark plug selection is essential for optimal combustion and performance development of the engine. Particular attention should be paid to the heat value according to the manufacturer’s specifications. Since each manufacturer defines the heat value differently, for example, a Bosch heat value of 3 may correspond to an NGK value of 9. As a guideline, the manufacturer specifications with alternately applicable spark plugs and their exact designations or type codes are listed in each vehicle manual.

We work with the official vehicle usage lists of the manufacturers and offer you exactly the right spark plug for your vehicle.

Caution is required when using suppressed spark plug connectors; double is not always better, in this case no suppressed spark plug should be used, as 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
