K&N Performance Gold® Oil Filters were originally developed for demanding auto race applications, our premium automotive oil filter is rapidly becoming a favorite among consumers for its durability and easy removal. 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. Heavy-Duty Construction for Extreme Conditions. To 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 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.
