K&N Stock Replacement Oil Filters
These oil filters were designed for high-performance engines and synthetic oils. They
feature a 17mm wrench nut for easy service. The nut is drilled for safety wire security. Other
features include thick-wall construction, strong inner cores, heavy base plates with double
rolled seals and improved pressure relief valves. The check valve prevents oil drainback and
dry starts. The modern synthetic-blend filter media catches more dirt, while still permitting
more flow with less pressure drop, and is unaffected by racing fuels.
