I just took in a used bullydog complete air intake kit. It is the RFI intake kit 51100. Says it fits all 6.0 diesels 03-07. Anyways I'll part with it for $200.00 (retail 329.99) Without a MAF sensor. $250.00 With a brand new MAF sensor (to make switching easy during warranty repairs) You can look at the bullydog website and see the product. I can post pics also. Think I might have a Power hungry chip for a 6.4 here soon.
