That's part of the problem---I don't know any BLC with an intake. Well, technically, the original air source would be the engine's intake. IMHO, what is being described as a "BLC" is not, and would be better served by the "active air flow control" terms we've seen before.
Still, I've never liked any of the extra slits Kawamori likes to put near the intakes, ESPECIALLY when they're said to involve control and not be merely a simple intake for some cooling etc.
