Royal Purple 20-500 Royal Purple 20-500 3" Spin-On Oil Filter

Royal Purple Extended Life Oil Filters provide superior particle removal. The high-performance and optimized flow characteristics of these filters means maximum performance for your vehicle. The micro-glass media that is 100% synthetic inside these filters give you superior particle removal with 99% filtration efficiency at 25 microns. Each filter features a high performance silicone anti-drain back valve that prevents dry starts, even in the most extreme conditions. An extra heavy duty rubber base gasket ensures a leak free seal. The ultra-strength filter housing endures higher burst strength than all other conventional filters.
