An automatic air intake temperature regulator (10) for regulating the temperature of air entering an engine (12) by varying amounts of ambient air and preheated air entering the engine includes a movable shutter (22). The shutter (22) is movable between a first position wherein the shutter closes an ambient air inlet (20) and opens a preheated air inlet (18), and a second position wherein the shutter (22) closes the preheated air inlet (18) and opens the ambient air inlet (20). The regulator (10) further includes biasing structure (48) for biasing the shutter (22) toward the first position. The regulator further includes temperature responsive structure (50) for sensing temperature of the ambient air and urging the shutter (22) toward the second position as the ambient air temperature increases.
