Hi all, need some advice on swapping my WRX intercooler with one from an STI.

1, can this be done

2, what if benifits is there to be gained

3, how difficult is it to do

Many thanks

Colm

Would make no difference, won't make it go any faster. You would just have a bigger intercooler that's all.

I replaced my WRX intercooler with an STI one. One difference being a larger surface area, colder air for the intake.
