K&N powersports 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 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.

Ordering was quick and easy. I do not know about the quality of the filter, only my engine knows, but I believe it to be good as I have used K&N products in my autos. What I really like is the hex nut on the end of the filter so I can get it off.
