An intercooler is, at its essence, a heat exchanger in turbo or supercharged engines. Its primary responsibility is to take the extract the charge heat, caused by turbo pressure increase, and releases it into the air like the car radiator. Cooler and denser air can then enter the engine and results in more torque and power.
