Love my K&N filter! I can feel the difference from the stock air filter a lot. I have to slow it down while driving. Can't even feel the speed I'm going. Over all I give this air filter 100%!! I'm glad I purchased it though. I would highly recommend it. I bought this for my 2012 scion XB.

Fast shipping and I'm stoked to have the best air filter in my car. I can't tell the difference, but I know it's making a positive impact on my car.

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.

Past experience with K&N filters prompted me with this order. Very quick response to my ordering and received within a week. Filters were exact fits and slipped right in. I bought one for my wife's RAV4 and one for my RAM 2500, both are pre oiled which saved the cleaning and oiling kit I also bought from being opened. I personally like the aerosol spray to the oil bottle, cause I just could not seem to get that light film of oil coating on the filter with the bottle ( just a personal preference ) Recommend these filters highly.
