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.

Product Reviews

  I use this filter on my Harley. Great product. Does it's job well.
Tom Grant Colorado
  The nut on the outside of filter makes it easy to turn on and off. The more finite filtration compared to original OEM brand is highly desired. 5 star rating my viewpoint.
Thomas Knutson Tucson, Arizona
  Meets or exceeds factory specs. Easy on easy off and looks good.
Fred Howard Yuma, Arizona
  The best thing about this product is no need for a special wrench.
Doug Edmonds Texas
