This 360-degree radial flow air filter features our pre-oiled Pro-GUARD 7 with 5-layers of progressive cotton media with 2-layers of synthetic media providing 99.7% cumulative efficiency for maximum filtration (US PAT 06811588). Our Pro-GUARD 7 media provides your engine with maximum protection with highest cumulative filtration efficiency for severe duty environments. This media is perfect for street and/or off-road use. Its inverted top makes for more filter surface area, resulting in longer service intervals. The smooth one-piece sealed housing, constructed of heat-resistant cross-linked polyethylene (XLPE), features our patented pending filter-to-housing interface.
