• Filters More Oil With Less Restriction!
• Withstands Up To 300 psi Of Pressure!
• Compatible With All Racing Fuels!

When tested to SAE j806, Moroso Racing Oil Filters produce a maximum initial restriction of only 2.5 psi! The result is less pressure drop, more flow, less oil bypass (when no filtration occurs at all), and maximum filtration performance that's so important in severe racing conditions.

Filtering out extremely small particles (20 microns or less) is fine for passenger cars with 10,000 mile service intervals - but not for racing or high performance street use! Low micron filtration reduces oil flow and pressure. And when too much restriction occurs, the by-pass valve opens, eliminating all filtration. Moroso's 27-micron element design insures full filtration with minimal restriction under the most severe operating conditions!
