An air intake assembly for a vehicle includes an air intake configured to intake ambient air and a heater box configured to be positioned adjacent a component of an exhaust assembly of the vehicle. The heater box is configured to intake ambient air and heat the air by heat absorption from the component of the exhaust assembly. The air intake assembly is configured to selectively permit passage of ambient air from the air intake and heated air from the heater box toward the engine assembly. The air intake assembly may selectively permit passage of ambient air and heated air by use of a valve in communication with the air intake and the heater box and further in connection with an engine assembly of the vehicle, the valve configured to selectively permit passage of ambient air from the air intake and heated air from the heater box toward the engine assembly.
