I use K&N air and oil filters on all my personal vehicles, currently being: Suzuki GSXR 1000, Cagiva Raptor 1000, Jeep Cherokee and Nissan Stagea. To keep them running in top order I won't go past K&N!!

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.

I replaced my factory Suzuki air filter with this K&N air filter and I noticed the difference immediately when the front end came up at the power band in third gear. This filter really does increase performance.
