  • 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.

K&N has a great web site. I used their vehicle search to find the correct filter for my Harley Davidson 103. I really like the nut on the end of the filter as it makes installation and removal easy, no special tools required. An overall excellent experience Fast shipping as well.

So disapointed that when I purchased one it said made in Korea. Going back to (brand name) filters, made in US.

Very impressed with the quick service, and having looked into choice of filters I settled for K&N as it is a proven quality product.

Good delivery time and looks great on my bike. I look forward to being able to use the nut on the filter on my next oil change. The stock filter was difficult to remove and I got oil all over the place. This filter will be easier and cleaner.
