From someone who has fitted a ram air system to a V6 FWD, yep it makes a difference.
And with small displacement motor, and the air only entering through the ram air vents, you damn well better believe you'll feel 300-400CFM being pulled in at WOT. Its pretty close to a small air blower that would be used in a home hvac system...the kind that moves air from your heater throughout your house.
