Which one did you order from Summit? I'm planning to run a 4150 on a 4500 intake (I have the intake and don't want to buy a new one, plus it has some extra porting done to it also). From the people I talked to so far I'm not sure its a good idea. Anyone else doing this and how is it working for you?
Debating whether I should break down and just buy a 4150 intake.
