  • 17 mm exposed nut designed for easy oil filter removal
  • Heavy duty construction for extreme conditions

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.

Have used K & N before and found their products to be of good quality. The bolt on the end of the filter made changing it a breeze, I didn't even have to remove the fairing lower panel as I normally would to do it. Brilliant!

I've purchased Polaris oil filters for my Sportsman in the past and lately I've had problems with leaks around the seal. I replaced with the KN-303 and no more leaks. Thanks!
