In Bosch Platinum spark plugs, a platinum plate on the center electrode ensures a longer service life and improved combustion. Unlike a WR8APP30T Bosch platinum spark plug, the center electrode produces a stable spark thanks to its fully coated ceramic layer, which significantly increases durability.
Note: For official MFK approval, the ignition system must include a noise-suppressed component. These spark plugs are noise-suppressed and can therefore be used on public roads in combination with a non-noise-suppressed spark plug connector.
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.
A high-quality product from the German manufacturer BOSCH, meeting original equipment manufacturer (OEM) standards.
