Intercoolers are generally only visible when a turbocharged car is installed. Because the intercooler is actually a turbocharged accessory, its function is to improve the engine's ventilation efficiency. For supercharged engines, the intercooler is an important component of the booster system. Whether it is a supercharged engine or a turbocharged engine, an intercooler needs to be installed between the supercharger and the engine intake manifold. Since this radiator is located between the engine and the supercharger, it is also called intercooling. The device is referred to as the intercooler.
