Thanks, Bowlgod.

The lower grille mod is exactly what Dulvalius said. It only works for the Roto-Fab style intakes. I believe you can do it to the stock intake set-up, but you also have to do the lower panel mod to go with it....or it will be useless. Once cut, it will act like a ram-air style.

I really dont have enough miles on this new setup to really tell yet if I have better mileage or not. I will have to monitor it over the next week or so.
