We've changed oil filters and several of our product development technicians are sportsman class drag racers. They insisted we offer an oil filter that corrected the headaches they experienced over the years changing oil filters. Our Oil Filters Have NutsWe 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. Our oil filters include a 1" nut welded to the top of the canister so they can be easily wrenched-off with a standard tool.  Durable Construction for Extreme ConditionsTo satisfy the demands of racers, our oil filter has many features over and above the requirements of most vehicles. We use thicker canister walls for extra strength and durability which reduces the risk of damage from loose rocks and debris. The durable 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 RateK&N oil filters have filtering media that allows for higher flow rates while providing outstanding filtration. High filter flow rates are important in racing Corvettes 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 OilsOur 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. WarrantyOur oil filters are covered by a limited warranty to be free from defects in materials and workmanship when installed and replaced using engine and equipment manufacturers recommended service intervals.
