Here's my thought.

The amount of air that could come through an average size Cobra hood scoop would easily support over 1000 HP. I'm pretty sure you can't get air much colder than air going in directly above the intake from the hood scoop. If air was routed from a lower location closer to the road surface it would be drawing in higher temperature air because roads are much hotter than the general air temperature. If a sealed forced induction was used it would complicate the engine management at higher speeds because of the huge load Cobras have with their terrible coefficient of drag.
