My car came with one like this and also has a small aluminum blade behind the duct to help catch a little more air in.  Now I actually need my motor in to see if it works.   :)

I'll try to get a pic tonight.  It is basically like a mini blade type spoiler turned around backwards.  The rule says that you can have 3/8" louvers as long as they do not direct air to the carbs.
