In order for the fuel-air mixture of the engine to ignite perfectly, a stable spark is required at the right time. Therefore, choosing the right spark plug is essential for optimal combustion and performance development of the engine. It is especially important to pay attention to the manufacturer's specification regarding the heat value. Since each manufacturer specifies the heat value differently, for example, a Bosch heat value of 3 may correspond to an NGK value of 9. For reference, each vehicle manual contains the manufacturer's specifications along with alternatively usable spark plugs and their exact designations or type codes.

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

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