you cant run an intercooler, as griff stated, its really only applicable to turbos.
Basically inlet charge heat on turbos gets silly, so an air-air intercooler works fine, it doesnt get down to ambient temps but lowers charge temps significantly from well over 150 deg C.
For a NA car, all you need is ducting to the front anda sealed airbox and you will be running close to ambient temps, and intercooler would do nothing.
