Originally developed for demanding auto race applications, these premium automotive oil filters are rapidly becoming a favorite among consumers for its durability and easy removal. K&N has changed oil filters and several of their product development technicians are sportsman class drag racers. Those drivers insisted K&N offer an oil filter that corrected the "headaches" they experienced over the years changing oil filters. So, as a result, the Premium Wrench-Off Oil Filter was born. It's Durable construction paired with a high-flow rate makes it a top choice among today's oil filters.
These 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. Most of K&N's canister-type automotive oil filters come with 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 Conditions
To satisfy the demands of racers, K&N's 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 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.
K&N oil filters have filtering media that 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.
