I would stay away from k&n not all oil filters but k&n specifically. I race dirt modifieds and some racers choose to use the k&n but thats mainly because they have never built an engine or pulled one apart after running a k&n they don't filter anything but large rocks. Also have a buddie that has looked at one of them under a microscope from the inside after running one on a quad and said that it was the worst out of all the other products out there. I'm just saying anything but K&n.
