Functional twin hood scoops

"They" say that those scoops that are low to the hood like that are not very effective, same with E-body Rallye hoods. Six pack hoods suppose to be better because they get up into the air more. Supposedly too close to the boundary layer or whatever. I haven't tried, it but I will when I get to that point. If nothing else I don't think it hurts. But, if you drive in the rain you may want to think about how to let water out before it gets to the carb or add a door with cable actuation, like some of the original scoops had.
