It’s true! There is a filter that stops more dirt, yet manages to crank out the same power gains as the leading paper and gauze performance filters. It’s the True Flow foam air filter.

The secret is a foam labyrinth of tiny interlock cells coated with a flame-retardant, non-drying oil. Dirt is trapped in the sticky twists and turns of the maze, never to find its way to your engine. At the same time, air breezes through the filter, which is 97% air itself.

Under normal conditions, the True Flow can go up to 50,000 miles between cleanings and oilings – True Flow Cleaning Kit with Foam Oil sold separately. Truth be told, the True Flow is the last air filter you’ll ever need.
