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.
