Bel-Ray Foam Filter Oil and Bel-Ray Foam Filter Oil Spray

Flex Your Engine with Bel-Ray Foam Filter Oil, an innovative foam filter oil for all street and off-road foam air filter applications.

Ultra-viscous formula forms an oil barrier to
trap micron-sized particles that can cause engine damage while
waterproof properties prevent clogging when wet.

The fast drying tacky-film eliminates the mess
associated with air filter maintenance and the aerosol makes it even
easier to use with its spray on no mess application.

Available in 1 liter and 4 liter bottles and 400ml Aerosol Cans.
