K&N Performance Gold® Oil Filters

Our Performance Gold Oil Filters use a cellulose media bound by phenolic resin surrounding a metal inner core that provides structural strength to reduce the risk of filter collapse. The resin is the "glue" that holds the media fibers together and at the same time keeps "pores" open by keeping the fibers apart. The resin is cured to full strength during the element manufacturing process. Phenolic resin systems are an excellent choice for the high temperature demands of oil filters. Our filter includes an anti-drainback valve, when applicable, that prevents oil from draining back into the crankcase during engine shutdown. The anti-drainback valve is useful in situations where the filter is mounted horizontally which could allow backflow. We use rolled threads to help prevent stripping during installation or removal and an internally lubricated gasket provides a positive seal even after the filter has been removed and reinstalled.
