Mike, Indianapolis, Indiana
Install was very easy. I have driven close to 2,000 in about 2 weeks since it was installed and have noticed around 2mpg increase in fuel mileage. Definite power increase while running A/C over standard air filter. Love it so far.

This is the second K&N replacement filter I have purchased and installed in my vehicles. Both have worked extremely well and improved performance as well as gas mileage in my vehicles. I highly recommend K&N filters.
Essy Lechon, San Antonio, Texas
This is the 4th new vehicle I have purchased a K&N filter for. Easy to install and a perfect fit.
