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.

Great value oil filter and good quality especially having the piece in the end making the next oil change so much easier.

An excellent oil filter for my ninja 650r. Has a nut on the end so you don't need a filter wrench attachment.

Hi guys. I don't usually write reviews on products often, but since I got time and buying an oil filter again. So this is the best and easiest filter to install and to replace in future. I only trust this brand on all my 3 bikes. Thanks for the great products.

The incorporated nut on this filter makes it easy to remove and install without special tools. I've used OEM filters in the past and they are a pain in the rear to remove and install.
