So first of all let me start by saying this thing does have a whistle noise even though it says its quiet. I do have a aftermarket intake and I'm not sure whether it makes it whistle more because of all the air coming in faster. Also I had to cut some plastic to make it fit because of aftermarket intake. Now for the mpg/hp/tq gains as far as the mpg I'm not too sure on that but I do have better throttle response and my truck gets going better than usual my truck does feel like it has more power.

Installation was fairly simple although if you have DBW you may need to use a longer hose for the coolant line that runs underneath throttle body. Saw a good increase in mpg did see a good difference in pick up midrange and was a good addition with the k&n intake. Well worth the $85. It does whistle but i only heard it when the radio was down.
