For all you people who remember ANYTHING from physics, you know that compressing a gas makes it hotter. And Hotter gases expand! so here you are compressing the air to get it into your engine, and it gets hot and expands again.

An intercooler is basically a radiator for your intake air... After the air is compressed by your turbo/supercharger, it goes through an intercooler, which allows the hot compressed air to cool down and contract a bit... That way, you can get more out of your FI system.
