I'm looking at buying a GoGo Diesel Stage 1 intake for my 2005 F350. I'm in the process of gathering all my parts for when the truck goes in for studs. I have no idea when I'll actually get it in the shop, so I don't want to mess with a core charge. I'm going to pick up a spare intake to send in to have done. My question is, what year models can I buy that will work on my 2005 6.0L? Isn't there a difference between the earlier models and the newer models? I just want to make sure a I buy a spare that will work for my 2005. Thanks in advance.
