Originally developed for demanding race applications, K&N's Premium Wrench-Off Oil Filter has become a favorite among consumers for its durability and easy removal. Most of our automotive and marine oil filters come with a 1 inch nut welded to the top of the canister so they can be easily wrenched-off with a standard tool. 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 drilled hole on the nut provides for safety wire attachment. Our oil filters also use a resin impregnated cellulose filter media. This allows for higher flow rates while providing outstanding filtration.

K&N Pro Series Oil Filters have been specially designed for professional installers and service providers. Their high flow design can help to improve engine performance by reducing oil filter restriction. Our Pro Series Oil Filters have a fluted canister shape so they can be removed with a traditional oil filter wrench commonly available to commercial installers. These Pro Series oil filters provide outstanding filtration and engine protection throughout their service life. They are engineered to handle all grades of synthetic, conventional and blended motor oils. The pleated media provides high capacity making them suitable for extended oil change intervals when used in accordance with the vehicle and motor oil manufacturers recommendation. K&N Pro Series Oil Filters are available for canister and cartridge type oil filter applications
