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.

Trouble-free installation, trouble-free operation. Every oil filter ought to be as easy to install and remove as a K&N.

An excellent oil filter for my ninja 650r. Has a nut on the end so you don't need a filter wrench attachment.
