K&N oil filters have nuts
We have all been there: Whether its 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. Each of our automotive and marine oil filters comes with a 1 nut welded to the top of the canister so they can be easily wrenched-off with a standard tool. Our motorcycle and ATV oil filters come with a 17 mm nut.
K&N filters construction
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.
