Intercooler

The intercooler is a device used to cool the air coming into the combustion chamber on turbocharged and/or supercharged engines. This is done because cooler air produces more power, and charged engines tend to heat the intake air while it's being compressed, thus decreasing its burn and combustion chamber fill-up efficiency. Most intercoolers have an air-to-air system, air-to-liquid system, or sometimes combination of both.
