Sti intercooler gains?

05rex · 03-10-2008, 11:16 PM

im looking into buying a sti intercooler to upgrade the stock unit that i have. ive got a 05 wrx just so there is no confusion. just curious what the gains would be such as less lag on the turbo and cooler intake temps. is it worth buying . i also have a spt intake and cat-back. tell me if this going to do anything.

it won't change a thing like both of the other mods you did

The two easiest to do power mods are Engine Management and a Downpipe. If you want more power, I'd recommend either or both of those.

ive heard that it will give me better spool up on the turbo because of the y pipe and cooler intake temps in the summer months. So is that not true?

I cant see how it would make you turbo spool faster, but it will lower you intake temps in the summer but hot enough that you'll notice much of a difference

i dont know about this for sure but i heard that the y pipe is better on the sti versiion versus the wrx version smoother and better flow

Gains from the stock to STi intercooler are minimal. Unless you're getting the thing for free or really cheap, it's not worth it. Save up and get a real TMIC upgrade if that's the path you're looking at.
