N20-A/PQ04 Intercooler Assembly

The N20-A/PQ04 is a charge air cooler (intercooler) designed to reduce the temperature of compressed air from the turbocharger before it enters the engine intake manifold. Lower intake air temperatures increase air density, improving combustion efficiency, power output, and reducing NOx emissions. This unit typically features aluminum bar-and-plate or tube-and-fin core construction with plastic or aluminum end tanks. It serves as a direct replacement component for specific OEM applications requiring this part number.
