yes, air is drawn through the front of the car and the hood vent allows for the air to leave the box. I would think that if it was closed up and a proper ram air setup utlized you would (at maybe over 100 mph) be forcing a slight amount of positive pressure on the airbox which would 100% be power making and noticeable. Keep in mind the bottom of the airbox also has a hole in it to drain water from that hole in the hood.
