In order for the gasoline-air mixture of the engine to ignite perfectly, a stable ignition spark is required at the right moment. Therefore, the right choice of spark plugs is essential for optimal combustion and performance development of the engine. Particular attention should be paid to the heat value according to manufacturer specifications. Since each manufacturer designates the heat value differently, for example, a Bosch heat value of 3 may correspond to an NGK value of 9. For reference, the manufacturer specifications with alternative spark plugs and their exact designations or type codes are listed in every vehicle manual.

We work with official vehicle application lists from manufacturers and provide you with the exact right spark plugs in a set for your vehicle.

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