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.

 Good product. Timely shipping. Thanks for offering it in gloss black. But you should send K&N stickers with every order.
Jason Roe, Manchester michigan.
 K&N oil filters are the best. They're very well made and you can use a socket wrench to take off the filter.
