I am in my 3rd RAV-4 in 17 years. I have used K&N filters in all. In my new 2015 XLE AWD, I installed the K&N filter about a month ago. I have since observed a quicker response to throttle input. While now indulging in the heightened responsiveness, I am still experiencing my previous average in city mileage of about 20 - 22 mpg. This is in line with the improvement I was anticipating.

Simply the best. I don't have many performance upgrade options at my disposal for my 2013 Lexus ES300h. K&N intakes and filters have always been a staple of my previous rides. This air filter boosted my mpg's by 2 after only the first tank of gas. Just wish they would have sent me a sticker with black print for a white car instead of the white print that I got.

I have used K&N products for several years. Great products.
