I'm with Xander, it's an honest enough question to ask, and how was he to know it's a an easy find on google, I've been able to find several answers on this forum much faster than trying to flit around on google.

As to your question, a turbo compresses air in the intake quite a bit, which causes it to be quite hot (I think upwards of 200F). Of course, engines dislike hot air, so you add an intercooler, which is basically a second radiator your pressurized intake air runs through, so it cools it down to around the ambient air temperature. That colder air can then give you more power, and not damage your engine the way hot air will.

Sorry if I overexplained, I'm not trying to talk down to you, but I wanted to cover all the bases.
