TECH BASICS INTERCOOLERS
Intercoolers are fitted only to turbo and supercharged cars, although not all forced-induction engines feature one.
The intercooler’s primary role is to reduce the temperature of the compressed air (often referred to as boost pressure) created by the turbo or supercharger before it enters the engine. This is because when air is compressed very quickly, it is also heated. Although compressed air/boost pressure is good for an engine, heat is not. The main concern here is that cylinder temperatures
