In order for the gasoline-air mixture of the engine to ignite perfectly, a stable spark is needed at the right moment. The correct selection of spark plugs is therefore essential for optimal combustion and performance development of the engine. Special attention should be paid to the heat value according to the manufacturer's specifications. Since each manufacturer indicates the heat value differently, for example, a Bosch heat value of 3 can correspond to an NGK value of 9. For reference, the manufacturer's specifications, along with alternative compatible spark plugs and their exact designations or type codes, are included in every vehicle manual.

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

Caution should be exercised when using suppressed spark plug connectors; doubling is not always better, in this case, a suppressed spark plug should not 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
