PC Racings FLO Oil Filter is the last oil filter you will ever buy! Made from laser-cut, medical-grade, 304 stainless steel micronic filter cloth, this filter provides 200% more filter area in many cases. The stainless filter catches items down to 35 microns, which is about 3 times better than most good paper or brass filters. Unlike glued paper filters, the FLO Oil Filter pleat seam is welded and able to withstand up to 600 degrees (F). The FLO Oil Filter maintains consistent flow under all conditions including extreme heat, the presence of water, and cold start ups where paper filters can flow so poorly that they often cause the bypass valve to open and allow unfiltered oil to enter your engine! This filter technology is widely used in all types of auto racing including NASCAR, Indy type cars, Formula 1 and in the Aerospace industry where filtration is of the utmost importance. In addition to all the other benefits, the FLO Oil Filter helps keep land fills free of old used filters. Super-strength magnet installed for magnetic pre-filtering. Superior filtration, 35 microns! Proven Aerospace, NASCAR, Indy, and Formula 1 technology. Unaffected by water, heat, or pressure. Easy filter element inspection. High flow rate. Environmentally friendly. Washable and reusable. Pays for itself.
