A system for managing engine intake air temperature, comprising: an internal combustion engine situated in an engine compartment of a vehicle and fluidly coupled to an air intake manifold configured to receive engine intake air, wherein the internal combustion engine is further fluidly coupled to an exhaust manifold via which exhaust gas produced by the engine exits the engine; an exhaust gas conduit fluidly coupled at one end to the exhaust manifold; an air flow control device having a first inlet, a second inlet and an outlet fluidly coupled to the air intake manifold; a first air flow conduit having one end fluidly coupled to the first inlet of the air flow control device and an opposite end arranged to receive therein air from outside of the engine compartment; a second air flow conduit having one end fluidly coupled to the second inlet of the air flow control device and an opposite end arranged inside of the engine compartment to receive therein air surrounding the engine, and wherein the air flow control device is configured to selectively control air flow from either of the first and second air flow conduits (34, 38) to the outlet thereof; a sensor (72, 76, 82) producing a temperature signal indicative of an operating temperature associated with the engine; and a processor configured to produce a control signal as a function of the temperature signal, wherein the air flow control device is responsive to the control signal to selectively control air flow from the first and second air flow conduits (34, 38) to the outlet thereof; characterized in that: the system further comprises: an oxidation catalyst having an inlet fluidly coupled to an opposite end of the exhaust gas conduit and an outlet, and a particulate filter having an inlet fluidly coupled to the outlet of the oxidation catalyst and an outlet fluidly coupled to ambient; and the processor comprises a memory unit having stored therein a minimum temperature value that correlates to a minimum temperature of the exhaust gas at the inlet of the oxidation catalyst that is required to allow dosing the exhaust gas upstream of the oxidation catalyst with hydrocarbons, the oxidation catalyst being configured to be responsive to the dosing of hydrocarbons into the exhaust gas upstream thereof to produce exhaust gas temperatures at the outlet thereof that are sufficient to regenerate the particulate filter, wherein the processor is configured to be responsive to the temperature signal to modify the control signal to cause the air flow control device to selectively provide for air flow from either of the first and second air flow conduits (34, 38) to the outlet thereof to maintain the operating temperature above the minimum temperature value stored in the memory unit. an internal combustion engine situated in an engine compartment of a vehicle and fluidly coupled to an air intake manifold configured to receive engine intake air, wherein the internal combustion engine is further fluidly coupled to an exhaust manifold via which exhaust gas produced by the engine exits the engine;
