"Real live engineering data says the actual inlets on the side of the Boxster are TOO LOW. If Porsche had moved them up on the sides of the car, they would actually flow more than the 50% they flow now."
Not only that, but you would not be sucking up brake dust from the front brake. All it takes is a couple of hundred miles of driving and a clean filter element is pretty well covered with the black dust.....
