I am not a mechanic nor do I have access to a dyno but my experience with my 2000 Dakota pickup with 4.7 and a cold air system, worse gas mileage for a while then it got back to the same and basically all I got was a cool noise from under the hood. My Durango R/T.....same thing but it never recovered the mileage so I took it off and my mileage got better, So I am assuming you guys are doing this for performance? 390 HP on the street how much can you afford in insurance?
For the hemi's 08 had the throttle body facing forward toward the front of the truck, but the 09's have it relocated and facing up toward the bottom of the hood.
