Although this filter was not the one K&N recommended, it is the one that fits my Kawasaki Ninja 2004 perfectly. I've never had a problem with a K&N filter. You guys rock!

I wish I had replaced the air filters MUCH SOONER... I own two Suzuki SX4 hatchbacks 2013's. Both cars got the same MPG. At best I was hoping for 2 possibly 2.5 MPG increase. The first tank after replacing the filters according to the on board computer I went from 25.5 to 33.8 MPG I was more than pleased. However after filling up with 7.5 gallons of gas, I had gone 279 miles. That works out to around 37 MPG!!! Nothing else has been changed. In the past when getting close to 250 MAX miles on a tank I would be looking for gas. Both cars have the same type of improvement in MPG. The acceleration is much better in both vehicles as well> There is a response now when pressing on the gas pedal. Money well spent and ROI is a no brainier as I'm already showing a major savings on gas.
