In order for the gasoline-air mixture of the engine to ignite perfectly, a stable spark is needed at the right moment. Choosing the correct spark plug is therefore essential for optimal combustion and power development of the engine. It is particularly important to pay attention to the manufacturer's specifications 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, the manufacturer's specifications along with alternative spark plugs and their exact designations or type codes are listed in every vehicle manual.

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

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