I have a spare 04 intake manifold for sale. It will fit any 04.25-07 superduty with the 6.0. Would be a great candidate for porting I will try and get pics later this evening. Asking $100+ shipping.
OK, just let me know. I personally like the cleaner look of the 05-07 elbow myself and that is what I replaced the factory one with but it does give one or two codes for not having the wiring hooked up.
