Large cylinder bores with a lateral spark plug bore have a disadvantage. The flame wall has to travel long distances, resulting in incomplete combustion, higher fuel consumption and poorer performance. Our SE Performance ignition system provides a remedy by upgrading to double ignition. In order to install such an ignition system, however, the cylinder heads must be provided with a second spark plug bore. Of course we offer this service in our mechanical workshop.

Conversion of the cylinder heads to a second plug hole for dual ignition. The thread size of the second plug hole is M12 x 1.25mm. We use as spark plug a NGK D 8 HA (deviate from the first plug).
