In order for the gasoline-air mixture in the engine to ignite perfectly, a stable spark is required at the right time. Therefore, the correct spark plug selection is essential for optimal combustion and performance development of the engine. Especially regarding the heat value, the manufacturer's specifications should be considered. Since each manufacturer specifies the heat value differently, for instance, a Bosch heat value 3 may correspond to an NGK value of 9. For reference, each vehicle manual lists the manufacturer specifications along with alternative spark plugs and their exact designations or type codes.

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

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