POWERFILTER
LIFETIME OIL FILTERS

This outstanding line of Powerfilter Oil Filters consists of billet style precision machined products made of aircraft quality aluminum. The filter element itself is a finely woven 45 micron stainless steel mesh that is easily removed and can be washed clean and reused. That's why we call it a lifetime filter. However, we do offer inexpensive replacement elements in case your original one becomes damaged or otherwise in need of replacement. We also offer replacement o-ring kits as well. Additionally, extra fine elements are available for racing applications. Due to the extreme fine mesh used (10 microns) these filters should not be used on the street and when used in racing applications should be cleaned after each race event. These filters also feature a pipe plug in the bottom so that oil can be drained from the filter before removal. This eliminates the problem of having oil run down your arm when removing the filter housing. This page lists the most popular performance engine applications. For a complete listing for every vehicle made since 1985, plus most earlier performance applications, go to the application chart.
