Item arrived 2 days after payment. Perfect replacement for my 2010 Yamaha xj6n after fitting an after market exhaust. It is like a fresh breath mint for my motorcycle, helps it breathe more easily.

Excellent product, fast shipping, excellent fitment on my 2005 Yamaha, Roadstar Warrior. Bike has excellent take off from the line and all threw the gears.

Excellent as always, this is for my 2014 Yamaha Zuma 125 (now it is a 160cc). I count on K&N to keep it clean for me.
