You may want to search the archives on the subject. There was a rather
detail discussion of a variety of air scooping devices about a year ago.
There was one character who apparently knew what he was talking about. Long
and short of it, the Vanagon scoops were almost as good as you could get.
Adding some sort of scoop or ear to the existing scoop creates a pressure
wave in front of the scoop, breaking the laminar flow into the scoop.

The dude who knew what he was talking about mentioned how 99.9% of scoops
on production cars, as well as IMSA and Indy cars are concave "laminar
flow" scoops, like our Vanagon, rather than old-fashioned convex scoops,
like you'd stick on the hood of your 6.6 liter Trans Am.

My Agenda: Vanquish Suburban Sprawl.
My Methods: Revitalize mature urban towns. Champion mass transit and fast
Internet service. Demand replacement of archaic, "separationist" zoning
laws with neo-traditional mixed-use zoning.
The Result: Exceptional living/working alternatives; restrained sprawl; our
children inherit walkable, beautiful, interlinked towns. Find out more at

If you force enough air into the intake, it would tear the air filter.
I don't know if such scoops would force enough air in to do that, but
it's something to keep in mind.
