This spark plug is not noise-suppressed and must therefore be used in combination with a noise-suppressed 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.
