Fresh air supply system

The present invention relates to a fresh air supply means (26) for an internal combustion engine (1), in particular a motor vehicle, with a filter element (37) which is arranged in a filter space (35), and with a charge air cooler (12) (in a cooler space 36) is arranged. An inexpensive manufacture can be achieved by a one-piece housing (34) having integrally the filter chamber (35) and the condenser space (36), wherein the intercooler (12) has a coolant inlet (61), a coolant outlet (62) and a the having coolant inlet (61) with the refrigerant outlet connecting (62) the internal coolant path extending with a housing (34) charge air path is heat-transmitting manner, which shall pass through through the condenser space (36).
