Installed a K&N air filter in our 2002 Toyota Avalon and got better idle quality, better acceleration and better performance in general. In 1971 I installed a K&N filter on my Yamaha motocross bike and saw an impressive gain in performance... needless to say, I've used them since that day.

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.
