I've always been very happy with K&N filters for all my vehicles. I ordered this one with free ground shipping. It was delivered in less than 24 hour! FANTASTIC!!! Thank you,.

I have used them before in my Jeep TJ. Outstanding. Abslutely the last air filter you will have to buy . Now I just traded for a different car and the first thing I did is replace the air filter with a K/N life time filter.
