For the gasoline-air mixture of the engine to ignite perfectly, a stable ignition spark is required at the right moment. Therefore, the correct selection of spark plugs is 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 specifies 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 with alternately usable spark plugs and their exact designations or type codes are listed in every vehicle manual.

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

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