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.

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.
