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
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.
