An intercooler is an intake air cooling device commonly used on turbocharged and supercharged engines. An intercooler cools the air compressed by the turbo/supercharger, reducing its temperature and thereby increasing the density of the air supplied to the engine. It allows the turbocharger to operate at higher boost pressures safely, thereby unlocking greater potential power output from the engine. Lowering Intake Air Temperature: Cools the high-temperature air compressed by the turbocharger through air-to-air or air-to-water heat exchange, preventing damage to intake sensors. Increasing Air Density: The increased density of cooled air allows more oxygen to enter the cylinders, improving combustion efficiency., Manufacturer: DGOINGPI
