What is it called when they have instead of a scoop...a heat extractor hood?

Cobras have them...as well as Mits Lancer Evo's

I think a Heat extraction hood would look hot on a contour...but there couldnt be any functionality unless it would be right over the radiator...and maybe reloacted a wide filter to the airintake.
