For the gasoline-air mixture of the engine to ignite perfectly, a stable spark plug is required at the right moment. Therefore, choosing the right spark plug is essential for optimal combustion and engine performance. Special attention should be paid to the heat range according to the manufacturer's specifications. Since each manufacturer specifies the heat range differently, for example, a Bosch heat range 3 may correspond to a NGK value of 9. For guidance, every vehicle manual lists the manufacturer specifications with alternatively usable spark plugs and their exact designations or type codes.

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

Caution is advised when using suppressed spark plug connectors; double is not always better; in this case, a suppressed spark plug should not be used, as the total suppression resistance would be too high.
