Is this a first mod to the truck cause this is one of the last thing you should do to it. Unless you're only instrested in the sound with no power benifit. Trying to throw more air into an engine without modding the fuel just screws up the mixture and messes with a tuned intake, I've looked and looked and don't see how you can get the air box any further away from the engine to get colder air, of course I can be proven wrong on that. Anyway you'd get more power by simple upgrading to a higher flow filter like k&n. you'd get more ponies from a high flow muffler, cheaper and easier to install.
