Clear View Filtration's Patented Dual Oil Filter Assemblies arethe Best Oil Filtration SystemAvailable. This 4" Screw-On Filter Assembly was designed for most Big and Small Block Engine combinations, includingStreet, Dirt and Marine use. This filter also has a single O-Ring groove for use with a System 1 filter. This filter is the best choice for motorsports ran on dirt and other applications where the user wants to filter microscopic and dust particlesout of the oil system. Also where space is limited and being light weight is important! Oil first flows through the See Through Filterwith a coarse 115 micron screen which traps all the larger particles that can be viewed and inspected while themicroscopic particles flow into the System 1 which has a finer mesh screen. 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 exposingthe element and filtered particles without draining or leaking any oil and without unbolting or loosening any fasteners or fittings. Filtersare 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.
