A List Member asked whether these air vents actually do suck in air, or vent
out air.  I am still not certain that anyone has answered this clearly.

I have followed this thread with interest, as I live in Austria now, and was
forced to remove my rear side running lights.  As these are now gone, there
is a nice large space, especially on the driver's side, where a cutout could
be made and a scoop could be constructed to pull air in while driving... it
could even be directed pretty much directly onto cylinder #3 if the design
was good.

Before I consider this for the left or right or both sides... it would be
good to know what really happens to the air as one drives.  If you create
airflow using scoops (and if it even works at all, is another question)
where does the resulting flow end up going... and does it result in bad
things, like creating backflow or vacuum areas anywhere.

How far out must one actually go, to obtain a successful "scoop" effect?
Would an inch end up pulling any air in??

Aerodynamics experts on the list... PLEASE set us all straight on this
mess... and deliver  the final word, so we all can get on with our lives.
