Charge air cooler (Intercooler) The engine employs a turbo-compressor to force air into the engine intake manifold and a charge air cooler to cool the compressed inlet air. The resulting increase in air flow raises pressure in the intake manifold and increases engine power over that developed by the normally-aspirated engine. The charge air cooler (which resembles a radiator) is located between the turbo-compressor and intake manifold. `` 275
