K&N powersports chrome canister oil filters contain a modern synthetic filter media, designed for ultimate flow with less pressure drop, yet engineered for outstanding filtration. K&N powersports 'spin-on' oil filters feature a heavy-duty, chrome-plated metal can. Most of these have a 17 mm nut affixed onto the end that allows for easy installation and removal. The 17 mm nut is crossed-drilled so racers can safety wire the filter to their bike.

Very pleased with the quality. I highly recommend this part. Having the nut on the end made the task of replacing the old filter very easy. The filter is located in a very tight spot, the nut made it so much easier to tighten.
