I have an 06 on order, a friend of mine has a slightly used afm intake (wife didn't like the turbo wistle) that I can get cheap. anybody have one of these? I am going to basically leave my truck stock for the first 50k miles, but the intake sounds like a good idea since it may help with MPG till then. At least the 06s already have the 4" exhaust, just have to do away with the cat, but staying away from chips and such till I have a big dent paid on this truck. Thanks
