The manufacturer went to the extent of putting the car thru a car wash to be sure it doesn't fall off (or leak?). They also said it helps keep the rear window cleaner. I doubt any wind tests have been made, not for the price of the product. So to that extent I guess it is a Race Inspired Cosmetic Enhancement.
There is a school of thought that shows a disdain for anything that does not benefit the performance of a car, for example fake scoops, vents, portholes, and large spoilers - e.g. David Patterson of "thatdudeinblue" and Alex Kersten of "CarThrottle." But that's just what they think.
The heat extractors on my Mustang are functional. However, I just couldn't help it on the wing risers though. They're so attractive.
