RAM AIR doesn't do anything on a turbo car, a free flowing intake will help the turbo's work less, but they are sucking air at a volume greater than ram air could every make any difference on. Ram Air would only help with a naturally aspirated motor by pushing in more air when the intake is under vacuum. That being said, those scoops are unlikely even to make a measurable difference at all on a N/A car.

So basically they are a cosmetic item at best and you can get them for $35-$50 from many other places if you just want them so there is something that looks red under the grill.

I am actually betting they disrupt and block airflow enough to the radiator to be detrimental overall to the car!
