For the gasoline-air mixture of the engine to ignite perfectly, a stable spark is required at the right moment. The correct choice of spark plugs is therefore essential for optimal combustion and engine performance development. Special attention should be paid to the manufacturer's specifications regarding the heat value. Since each manufacturer defines the heat value differently, for example, a Bosch heat value of 3 may correspond to an NGK value of 9. Manufacturer specifications for alternative spark plugs along with their exact designations and type codes are listed in every vehicle manual for reference.

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

Caution is advised when using suppressed spark plug connectors; double is not always better, and in this case, no suppressed spark plug should be used as the overall suppression resistance would be too high.
