K&N 33-2438 Air Filter Product Reviews

Perfect fit, noticeable increase in horsepower especially while traveling in the mountains of NC. Just finished first tank of gas following replacement and seeing a 1 1/2 mpg improvement. Did the replacement at the recommendation of the Toyota dealership to improve engine performance without compromising warranty. Will be ordering a filter for my wife's car.

Have always used K&N filters. Extreme value, helps boost performance and usually squeaks out an additional mile or two per gallon on fuel.
