Clear View Filtration's Patented Dual Oil Filter Assemblies are the Best Oil Filtration System Available. This 4" Screw-On Filter Assembly was designed for most Big and Small Block Engine combinations, including Street, Dirt and Marine use. This filter is the best choice for motorsports ran on dirt and other applications where the user wants to filter microscopic and dust particles out of the oil system. Also where space is limited and being light weight is important! Oil first flows through the see through filter which the element traps all the larger particles that can be viewed and inspected while the microscopic particles flow into the disposable filter and are filtered out. The clean filtered oil flows out of the filter assembly through the outlet opening back into the engine. A shot of air empties the filter in seconds exposing the element and filtered particles without draining or leaking any oil and without unbolting or loosening any fasteners or fittings. Filters are remotely mounted and can work on many applications including diesels. This dual stage filter will extend the life and flow of the disposable filter and still allow visual inspection of filtered particles for engine inspection.

The 4" Screw-On Filters have 2 Inlet and 1 Outlet Port openings that are threaded for #12 O-Ring Boss - 1-1/16-12 TPI fittings. The Inlet and Outlet openings have been machined to 0.625" or 5/8" inside diameter so it will not restrict fluid when using #12 lines.
