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.

Excellent on-line experience, fast shipping, great product. I have three motorcycles and use K&N air and oil filters in all three. I love the welded on nut, it makes changing the filter a breeze.

I haven't fitted the filter yet, so I can only comment on the order process which was prompt and efficient.
