FRAM Racing Oil Filters are optimized for both racing and high-performance street cars, and are compatible with all oil types. The heavy-gauge tapping plate and extra-thick steel can will withstand the high-pressure flexing caused by demanding driving conditions. A spiral-shaped center tube provides protection against collapse, and tough steel end caps add even more durability. A screen-over 22 PSI filter bypass valve provides additional protection against larger contaminants. Low-restriction racing media designed for high oil flow features 94 percent efficiency at 20 microns for excellent engine protection. Maximum operating pressure: 200 PSI.
