K&N Oil Filter Products

Premium automotive K&N oil filters provide high flow rates while providing excellent filtration and engine protection. High filter flow rates are especially important in racing vehicles where heavier grade oil is used and the oil is pumped through the K&N oil filter much faster than in a standard vehicle. K&N premium oil filters are engineered to handle all grades of synthetic, conventional and blended motor oils. K&N manufactures automotive oil filters for most vehicles on and off the road.

K&N Oil Filter Products have High-Flow Rates

Our K&N oil filter media is a resin impregnated cellulose. This allows for higher flow rates while providing outstanding filtration. High oil filter flow rates are especially important in racing vehicles where heavier grade oil is used and the oil is pumped much faster than in a standard vehicle. When the engine is circulating oil at high GPM rates, the high-flow K&N oil filter helps reduce the loss of pressure through the filtering process.

K&N Oil Filters are compatible with the Latest in Synthetic Engine Oils

K&N oil filter products are ideal for high-end synthetic motor oil. Synthetic motor oil is said to offer improved flow performance at cold temperatures while providing superior protection against thermal degradation.

Engine and equipment manufacturer's warranties remain in effect when K&N oil filters are used.

K&N Oil Filter Tech Talk

K&N Oil Filter products 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.
