Performance Silver oil filters by K&N are constructed from a high-flow design that helps to improve the engine performance by decreasing the oil flow restriction. K&N performance silver oil filters have a fluted canister shape so they can be removed with a traditional oil filter wrench commonly available to commercial installers. K&N performance silver oil filters are engineered to handle all grades of engine oils and provide outstanding filtration and engine protection throughout their service life. They comprise a pleated filtration media that provides high filtration capacity, making them suitable for extended oil change intervals. Performance Silver oil filters are available for canister and cartridge type oil filter applications.
