I am building up a list of upgrade parts to our WRX. Once I have them all I will get them fitted and then remapped. Will a STi Version 3 or 4 fit onto our WRX? If not which is a good upgrade TMIC for a wrx.

 

there is not point as the sti 3/4 intercoolers are smaller than a standard wrx cooler you would need a sti 7/8/9 top mount sold for £150 usually, also the sti3/4 intercooler will not fit

thanks scott pm me if you are wanting a sti 7/8/9 intercooler
