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 KN-138 Oil Filter Product Reviews

I was hesitant to try this because almost every site I visited (Brand Names) showed that this filter doesn't fit a 2014 Suzuki GSXR750. Took a leap of faith since this site said it would, and I'm glad I did. The bike just feels better. The price is right too.

Purchased for 2009 Susuki SV650. Perfect fit, very easy to tighten thanks to the nut right on top of the filter. Haven't put any real miles on it yet but the little I have since installing has been trouble and leak free. Another quality K&N product.
