Don't do it. Its a waste of money. I ran one on mine (K&N) for over a year. Started reading that they were useless and decided to take it off and go back stock to see the difference. I would have bet a million bucks the K&N would be better.......... and LOST!!!!! I immediately noticed that my truck ran a lot better stock. Better fuel mileage, too. Do a search and you'll find everything I did that convinced me its a joke.
