P037 is an ultra-fine, waterproof air filter developed specifically for use in demanding conditions such as dirt, water, and dust. Ideal for Dual Sport motorcycles, or for any application where performance AND extreme engine protection are of equal priority, P037 can filter debris as small as 37 microns while providing airflow equivalent to our class-leading P08 road/race filter.

The performance of P037 has been proven in testing at the Bonneville Salt Flats, breaking the world record on a BMW GS1200, and in the Bahrain Superbike Championship, where P037 has been chosen exclusively to cope with the dusty conditions.
