Ram air is different from a cold air intake. Ram air is a kind of forced injection; the faster the car goes, the more air is forced into the intake, allowing the engine to burn fuel faster. Ram air does give you the advantage of having cold air enter the intake, but I think that the greater advantage is the increased amount of air that's supplied to the engine.
