Thats a FMIC or front mounted intercooler. (real life examples) The mitsu Evo has a FMIC as standard, which differs to the Subaru Impreza which has a TMIC or top mounted intercooler
It doesnt take any air in. It has been mentioned that is a radiator. Well in a sense it is, but a radiator is for cooling the water in the cooling system. Any air being taken in, is induced through the airbox or induction feed.
An intercooler, cools the air and exhaust gas mix, that is fed back into the engine from the turbo.
Turbo and Compressor (supercharge) vehicles have intercoolers.
Hope that clears that up.
