hey i realise this is a total noob question but thought i just ask anyways. alright my new front bumper is awersome and gives me heaps of room for a intercooler. but i need to upgrade to a beter looking one because you can now see the black stock one. question is do you need a turbo to have a aftermarket intercooler??. also wats the difference between a intercooler and a radiator. yea i know lol.
