Side intake acting as venturi?

Visually, looking down the side of the car, you can see that the intake vent presents a certain amount of its cross section (although at an angle) into the airstream flowing around the car. It looks like it catches air so it is not likely that a negative pressure or suction could be created a the air box entry.
