I've heard two reasons. The first is pretty clear: air for the driver/navigator. The other I heard (don't remember where) is to induce positive pressure in the cabin. A lot of the rally stages have a bunch of dust, and you don't want all that coming into the cabin. So having an air intake way up high keeps a bit of positive pressure in the cabin to keep anything from coming in from anywhere but that intake.
