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

Why struggle with an oil change? Get yourself a K&N oil filter 17mm socket on the end and it comes off so easy. Plus I can get it so quick direct, ordered Monday night, sent next day and arrived wednesday morning. So I know it is genuine and going to protect my engine and not a fake. Happy customer.

Best Quality and value on the Market, have been using K&N Filters for at least 25 Years. Highly Recommend the online site, better value and quicker than my local dealers.
