I have been using K&N air filters for many years in my auto's so I figured why not put one in the ATV. Rocky Mountains vehicle specific items matched this filter to my ATV and it was a Perfect Fit! Thanks RockyMountain.
I got a K&N air filter for my crf250l. Using this stuff to clean it after I take it out for a trail ride has made it a BREEZE. Even when it's filthy. This stuff is awesome! And the directions are super simple!
