Note: For an official MFK approval, it is necessary that the ignition system has a de-rotated component. This spark plug is deflashed and can therefore be combined with a non-deflashed spark plug connector on public roads. Before purchasing, use the downloadable spark plug overview to check which type is best suited to your setup.
Alternative plugs and connection material for your ignition system can be found in the accessories section.
