What would pressurize that air? Because of Bernoulli's principle, I 
would expect that area to be slightly less than atmospheric. Perhaps 
the thinking is that the louvers "catch" the air and force it in. 
I'll admit that I've never measured the pressure there, but it would 
be easy to drill a hole in the brain mounting plate to check this.

Later on you mention scoops. I've often wondered if they actually 
help. That could also be measured.
