ized air from the turbocharger then flows forward
through the charge air cooler (intercooler) located i n
front of the radiator. From the charge air cooler (in­
tercooler) the air flows back into the intake manifold.
The charge air cooler (intercooler) is a heat ex­
changer that uses air flow to dissipate heat from the
intake air. As the turbocharger increases air pres­
sure, the air temperature increases. Lowering the in­
take air temperature increases engine efficiency and
power.
