K&N RU-2580 Universal Clamp-On Air Filter Product Reviews

Thursday, May 5, 2016 - Part RU-2580

Worked perfect as expected from K&N.

I bought this for use on an ATV CVT air inlet snorkel on hopes of reducing wear on the belt and clutches. K&N's ability to provide a free flowing filter far surpasses any expectations one may have. Without using any type of flow meter it appears that the air intake has not been impeded in any manner. This ought to do the trick.

Exactly what I needed. Looks great and performs perfectly. Thanks again.
