KNN Canister Type Oil Filters

• Drilled safety wire holes for racing in canister oil filters
• Most have sturdy 1 inch; (automotive) or 17 mm (motorcycle) wrench nut, where applicable, makes oil filter removal quick and easy
• Heavy-duty construction
• Resin-impregnated filter media provides maximum filtering surface for contaminant removal
• Anti-drainback valve (where applicable) eliminates dry starts, prevents oil from draining back into crankcase during engine shutdown
• Internally lubricated gasket provides positive seal while allowing easy on and off of filter
• Rolled threads provide extra protection against stripping

KNN Performance Gold® Oil Filter
Originally developed for demanding auto race applications, K&N's premium automotive oil filter is rapidly becoming a favorite among consumers for its durability and easy removal. We’ve all changed oil filters and several of K&N's 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.
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. Most K&N canister type automotive and marine 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. Most K&N canister type motorcycle and ATV oil filters come with a 17 mm nut.
High-Flow Rate
K&N 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.
TECH TALK
K&N's Performance Gold Oil Filters use a cellulose media bound by phenolic resin surrounding a metal inner core that provides structural strength to reduce the risk of filter collapse. The resin is the "glue" that holds the media fibers together and at the same time keeps "pores" open by keeping the fibers apart. The resin is cured to full strength during the element manufacturing process. Phenolic resin systems are an excellent choice for the high temperature demands of oil filters. K&N oil filters includes an anti-drainback valve, when applicable, that prevents oil from draining back into the crankcase during engine shutdown. The anti-drainback valve is useful in situations where the filter is mounted horizontally which could allow backflow. We use rolled threads to help prevent stripping during installation or removal and an internally lubricated gasket provides a positive seal even after the filter has been removed and reinstalled.

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. K&N uses 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.
