Originally developed for demanding race applications, the K&N Premium Oil filter is rapidly becoming a favorite among consumers for its durability and easy removal. Many of the K&N Technicians are racers and they insisted that the company offer an oil filter that corrected the “headaches” they experienced over the years changing oil filters. K&N Oil Filters Have Nuts We have all been there: Whether it’s remembering where that disappearing canister tool is; or having oil leak all over your garage and yourself; or finally giving up and pounding a screwdriver through the filter just to get if off. Where applicable, K&N ATV oil filters come with a 17 mm nut welded to the top of the canister so they can be easily wrenched-off with a standard tool. Heavy-Duty Construction for Extreme Conditions To satisfy the demands of racers, the K&N oil filter has many features over and above the requirements of most vehicles. They use thicker canister walls for extra strength and durability which reduces the risk of damage from loose rocks and debris. The heavy-duty construction will withstand higher oil pressures found only in racing environments without bursting. The drilled hole on the nut is for a safety wire attachment. Required for many types of racing, the safety wire prevents blown oil filters from falling on the track and representing a hazard to other race vehicles. This extra engineering offers peace of mind for consumers who want only the best. High-Flow Rate K&N ATV oil filters use resin impregnated cellulose filter media. This allows for higher flow rates while providing outstanding filtration. High filter flow rates are 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 oil filter helps reduce the loss of pressure through the filtering process. Compatible with the Latest in Synthetic Engine Oils K&N oil filters 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.
