  • 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
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.

K&N KN-171B Oil Filter Product Reviews

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

Great service from K&N and so much easier to get off with the 17mm nut on the end, there is not a lot of space around the filter on my bike and other methods have never worked well. I also suspect that the K&N sealing ring is a better quality and less likely to jam the filter onto the motor. Unfortunately it did not prevent me from missing the pan when I drained my old oil while still managing to drop the drain plug in the pan. I was also able to kick the pan across the garage floor spilling half the contents. Hat-trick PS I am a robot and feel it is discriminatory that I cannot post without clicking to say 'I am not a robot'
