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 removal. The 17 mm nut is crossed-drilled so racers can safety wire the filter to their bike.
  • O/E replacement oil filters for most cars, trucks, SUV's, motorcycles, & ATV's
  • 17 mm exposed nut designed for easy oil filter removal
  • Heavy duty construction for extreme conditions
  • Anti-drain back valve (where applicable) eliminates dry starts, prevents oil from draining back into crankcase during engine shutdown

I ride a Harley Davidson Lowrider s and I do my own oil changes. It is difficult to remove the Harley oil filter because there is no room to use a filter wrench. With this filter not only do I get the best filter on the market, I get the easiest filter to remove with a hex socket.

Oil Filter so much easier with a 17mm nut on the end. I have a k&N air filter also, great products.

My experience with the K&N online store was great. I was able to find the filter right for my bike. Completing the order was easy and I received my oil filter when promised. I will definitely use the online store again. Tim Millard
