I don't mean to hijack this post, but something I gotta ask. If the ram air thing works as does the cold air intake, then why do these aftermarket companies sell what they call cold air intakes that are really just open air elements that are open under the hood? Won't those so-called cold air intakes just pull in the hot air from under the hood? I would think that in this case, the factory intakes would outperform these aftermarket systems, wouldn't they?
