Eddie Zimmerman, College Station, Texas
Bought it for my friend for her FJ Cruiser. It is dusty where she lives and the duration of an air filter for her is very short. She cleans her's out regularly and loves the increase in gas mileage and performance it gives her. She was surprised that it cost less than $50 and does so much for her travels. She was thinking about getting a new vehicle, but not now that her FJ is performing so well!

The K&N air filter arrived on time, exactly as described on the Web site, in good condition, and performs flawlessly after almost 5,000 miles. Based on past experience with K&N, this will be the last intake filter I purchase for this vehicle.

I noticed a drastic change in the amount of gas my truck uses! Great investment for such a great price. Will be replacing air filters on all my rides.
