Bel-Ray Foam Filter Oil's new and improved formula is ultra-viscous for the highest levels of engine protection and fast-drying for more convenient maintenance.
It creates a highly tacky barrier for superior filtration without restricting air flow. Able to trap micron-sized, airborne particles that can cause engine damage and performs exceptionally well in dusty environments.
Bel-Ray Foam Filter Oil is waterproof, so it will not wash off, clog or gum up when the filter gets wet. Delivers all of the performance benefits of Bel-Ray's pour type oil in an environmentally friendly aerosol package.
