air filter Polini D.37 straight air box 37mm chromed blue

Polini Racing Boxed air filters are suited not only to the race track, but also to daily use in varying weather conditions. The addition of the dirt and water insert makes this tuning filter into a true allrounder. Filters for performance applications are susceptible to moisture and the protective insert prevents any potential ingress. Delivery as pictured, including protective dirt and water insert. Note: we recommend moistening the air filter with filter oil prior to initial installation. The protective insert is secured in position and can only be removed with a screwdriver. Connection: 37mm, straight. Total length: 100mm. Width: 80mm. Suitable for PHGB carburetors. Colour: blue-chrome surround with black filter foam.
