Being that the intercooler is placed near the very front of the hood, the largest portion of lift (as shown on an FC here) will actually turn into a bit of downforce as air is drawn out of the engine bay. It'll effectively shrink my frontal area. Another way I can reword this is that there is a very high pressure region at the front of the car (and front of the fender wells) and by placing a hood duct at the front of the car, it'll draw that air through, lowering that pressure.
