Collection: Intercoolers

The primary purpose of an intercooler is to cool the air that the turbocharger or supercharger has compressed before it enters the engine. By cooling the air, the intercooler reduces the chances of knocking and allows for more air to be forced into the engine, which can increase power output. An intercooler can increase horsepower output in turbocharged or supercharged cars but will not make a significant difference in naturally aspirated engines. There are two main types of intercoolers: air-to-air and air-to-water intercoolers.
