Intercoolers are pretty simple bits of kit - metal box with fins/tubes etc., just there to cool the air down after the turbo... Got an inlet, and an outlet, and that's pretty much all you need to worry about if you're replacing with an OEM part. Warm air goes in one side, cooler air comes out the other.
Turbos are simple enough too... Just a type of fan/compressor that forces air into the engine.. When you force (compress) gas, it gets warm... So you put the warm air through a big metal box with fins (intercooler) to cool it downbefore it gets to the engine... Simple!
