Review on KN 170 Harley Davidson Performance Filter by Jared Coleman

I've been using K&N air and oil filters on my Sportster since I've had one. This oil filter has always done its job. I change the oil and filter every 3000 miles and this filter makes the job easier. I love the "twist off" option on this filter, although the last one I ordered was slightly different in size and the regular 7mm wrench I use every time I take the filter off and I use one Had to use rubber filter wrench to remove it. . It was kind of an inconvenience, but not that bad. In general, the filter is of good quality.
