The right side vent is not a engine intake duct it is actually for engine cooling. There is a big electric fan at the end of the duct which evacuates engine compartment air for cooling the engine bay; hot air comes out of the vent in this case. It will come on if the bay gets too hot. It shouldn't be on all the time. There are engine coolant radiator fans up front as well
