Ok again posting for a friend with a prety much stock 06STi. Only mod he has in CAI and strut tower braces.
He isn't planning on modding the exhaust.
He is trying to decide on his next mod and he is torn between a tune and this intercooler.

Will the intercooler give him any power over the stock cooler? If so how much. Which is a better next mod to get? Thanks for any help.
