So far I have had a great experience with K&N. After installing my new air filter, I can definitely feel the difference in my car performance. I will highly recommend K&N and continue using such high quality product.

Obtained this air filter to enhance the performance/fuel economy for my 2011 RAV4.  I do most of my driving under 50 mph, which was using gas pretty fast.  Installation was a little bit tricky-you have to carefully place it in without tearing out wires.  After a week of disappointment, I remembered to reboot the cars computer it was stuck showing 21.1 mpg.  With my current tank of gas I am showing more than a 2.5 mpg improvement so far-pretty good considering its the V6 AWD model. And, the filter is guaranteed for beyond the life of this car, so I am definitely satisfied.
