Note: For official MFK approval, the ignition system must include a spark plug with an integrated spark plug cap. This spark plug does not have an integrated spark plug cap and must therefore be used in combination with a spark plug cap when driven on public roads. Before purchasing, use the downloadable spark plug overview to check which type is best suited for your setup.
You can find alternative spark plugs and connection hardware for your ignition system in the accessories section.
