Pro Design Yamaha Rhino 660 (2004-07) Pro Flow K&N Filter Kit

The K&N Pro Flow Kit from Pro Design is one of the most popular and in demand performance products available. The trick is the billet base plate which dramatically improves performance by directing and channeling air flow at a much higher volume for superior power gains. Unlike the stock design, the billet base plate with positive O-ring seal provides an absolute barrier against sand and debris. This kit can literally save hundreds of dollars in engine repairs. In dry riding conditions the Pro Flow Kit allows you to completely remove your airbox lid and maximize your air intake equaling unmatched air intake levels.
