The air-to-air intercooler is chassis mounted in front or next to the radiator. Air from the turbocharger is pushed through a network of heat exchanger tubes prior to entering the valve cover/intake manifold. Outside air flowing over the tubes and fins serves to cool the charge air. ‪

The resulting cooler intake air is denser than uncooled air, which results in additional air entering the cylinders so that additional fuel may be injected to increase output power. See Figure 31581 . ‪
