•  For improved accelerator pedal response, the intake air passage capacity to the separate type water-cooled charge air cooler of the SKYACTIV-D 2.2 has been reduced by half from 8 L {8 US qt, 7 Imp qt} to 4 L {4 US qt, 4 Imp qt}.

•  In addition, a water-cooled type charge air cooler has been adopted with an exclusive engine coolant circuit and an electronically controlled water pump to supply a constant, optimum amount of intake air temperature.

•  The charge air cooler is built into the intake manifold, and it differs from the SKYACTIV-D 2.2.

•  Two radiator caps with differing valve opening pressures, one for the engine cooling and the other for the charge cooler, are in the engine compartment.
