how does the intake manifold make the intake better? Is it really so cost effective while upgrading.

Say, consider this. 2 cars are making bench marks, both the same greddy turbo w/intercooler. ok cool. The only difference between the ls greddys on that one has a skunk2 intake manifold, the other uses the oem ls manifold.

Seriously, at the end of a quarter mile how many car lenghts is this?

ya and is the cash really worth the money.

 

On a turbo car, if the new intake manifold has a large plenum, I could see the advantage, but probably only at high rpm/high boost levels.. Otherwise, don't waste the money.

That's just my opinion.

 

On some setups it just makes more sense to turn the boost up a psi and be at the same point.
