Okay, might be stupid, might only gain me something like 5-10 HP, but hell i see used subaru intercoolers on ebay all the time for 5 bucks. question is:

Would it work, and would it hurt my engine somehow i can't think of. cold air, right?

Also, how much of a restriction would this be? I am running a stock air-box with K&N, soon to be de-snorklefied..... but how much would this hurt my low-end power, and would my this even work on my car?

more info, its a JDM EJ20T intercooler
my car: 99 Legacy 2.5GT Lmtd

The restriction you will see because of the intercooler will outweigh the gain.

The reason why you add an intercooler for a forced induction is because you get a gain 30-40% power gain because turbo and supercharger air is heated up so much from the pressurisation and hot turbo/sc. Its way hotter than ambiant air temp. because of the exhaust and friction from the turbine and pressurisation itself heats up the air. With a N/A motor the air temp in the intake is not much hotter than ambiant air temp so you dont/can't cool it off without a nitrous fogger.

An intercooler or aftercooler doesn't cool the air below ambiant air temp.

sticking a big restriction in your intake will hurt performance quite a bit.

ok, thanks, didn't know the I/C only cooled to ambient temperature, thanks
