To be completely honest.... I'm not sure if you'll hit the power levels where any of those intakes would see any significant gains. There aren't a lot of great options for intake manifolds for the 4.6 to start with either.

with comps you dont need anything other than the stock pi manifold. You have to be spinning your motor upward of 6500ish to really see the benefits of an aftermarket intake. The stock pi manifold is really pretty good, its only downfall is its plastic.

f that...i replaced it with a good old metal one...i want to at least pretend it wont fall apart on me...Altho heat soak is more of a problem, only on warm/muggy track nights though. but yea dont replace it until you have to at least.
