An air-to-air aftercooler or heat exchanger for a vehicular internal combustion engine, which is independent of the main vehicle heat exchanger or radiator, and which is located at a position upon the vehicle which is remote from the main vehicle heat exchanger or radiator, has a filter for filtering ambient air; at least one aftercooler heat exchanger, separate from the main radiator heat exchanger and disposed upon the engine at a location remote from the main radiator heat exchanger, and having a first passageway defined therein which is fluidically connected to the filter for receiving the ambient air which has passed through the filter; a second passageway defined within the at least one aftercooler heat exchanger for receiving turbocharged air from the turbocharger, for conducting the turbocharged air through the at least one aftercooler heat exchanger such that the turbocharged air undergoes a heat exchange process with the ambient air, and for conducting the turbocharged air to the engine intake manifold; and a fan for causing the ambient air to pass through the filter and the first passageway of the at least one remote aftercooler heat exchanger, and for causing the ambient air to be discharged to atmosphere.
