For the gasoline-air mixture of the engine to ignite perfectly, a stable ignition spark is needed at the right time. Therefore, the correct choice of spark plug is essential for optimal combustion and performance development of the engine. Particular attention should be paid to the heat value according to the manufacturer's specification. Since each manufacturer defines the heat value differently, for example, a Bosch heat value 3 can correspond to an NGK value of 9. For reference, the manufacturer's specifications with alternatively applicable 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 spark plug suitable for your vehicle.

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