While I agree with you about the fake scoops for the most part, let's not forget that back "in the day" most of the hood scoops were fake, too. Or at least on the base level musclecars. IIRC, even the hood scoop on the heralded first-generation Shelby Mustang was non-functional.
That 2% horsepower increase with the "Ram Air" is very debatable. Adding that many twists and turns to the air charge on its way to the MAF just might have the opposite effect that you're looking for. There's a ram air hood with snorkels on the leading edge of the hood (similar, somewhat, to the WS-6 'birds) that is probably the closest thing to well-functioning ram air for our cars. But to spend that kind of money for something with such a small increase in horsepower, if there's an increase at all.....well, there are lots better things to spend your money on. A cowl hood that will likely decrease underhood temperatures and possibly increase airflow through the cooling system is probably a better bet for a power increase.
