I'm very happy with the ordering process and with the K&N air filter. I've used these filters for years and have always been happy with them. I only wish I'd gotten this order in a couple days earlier, as I just barely missed the free hat with order over $50 promotion.

This is my second one, the first was for a Highlander, that I kept for 10 years. I think all keep this one as long.

I always buy a K&N filter when I purchase a new car. The "not having to service it" is the thing I like best. Better fuel mileage is an added benefit.

Seems to make more power and probably increases gas mileage, but I haven't had it long enough to find out yet. So far no complaints. In the future do you offer Viet Nam veteran discounts?

This air filter along with the cabin filter is my standard practice for all my cars. Once I change the filters, that's it, for as long as I own the vehicle. I have been using K&N since there was a K&N. I have retired after 55 years of selling industrial filtration equipment. These are of the same design we used.
