2011-2014 F150 5.0L S&B Cold Air Intake

I was very impressed. I felt the performance increase immediately, even felt a little rumble under the hood. After having swapped out my stock tires and wheels for some 33X12.5 on 20X10 I had lost some mileage. Once I put on the S&B cold air intake, with the help of the guys at MAK, I gained it all back and some. Definitely worth the money.
