Amazing improvement in performance over the stock filter on my son's 2010 Ninja 250. The Ninja has an inherent throttle lag, but this filter minimized that, almost makes it not noticeable. Awesome ! Stephan

Good filter. notice a positive difference in the 8k-11k rpm band (55-70mph), and I also notice an increase in gas mileage.

Like always, when it comes to K&N all you can expect is the best quality products. Ordered both the air and oil filters for my 2010 Kawasaki Ninja 250r and can really say I am very pleased with my purchase. Oil filter comes with both o-rings needed and air filter even comes with the sealant cream. Products work great and I will always do business with them. And also thanks for the stickers :)
