 This is my first K&N Air Filter for my 2013 Toyota 4Runner SR5, and I already notice a huge difference in gas milage! K&N has hit the nail on the head with their filters! I will be purchasing more K&N products in the very near future! Thanks!

 This is the 4th new vehicle I have purchased a K&N filter for. Easy to install and a perfect fit.

 By far, the best air filter product on the market. I haven't used stock filters in many years on either cars, cycles or trucks. You cannot do better than K&N for the quality and pricing of their products.

 I installed the K&N filter in our 2012 Toyota 4Runner and noticed an immediate improvement in power, plus we gained 1 to 2 mpg!  I have been using K&N filters for many years now and have been extremely happy with the results.  In fact, I just purchased a used Ford pickup truck and intend to replace the stock air filter with a K&N filter.
