The Aeroware vents were originally made and sold by
www.standres.com .
As far as I know, they are still being sold:

In the aeroware kit the side skirt and vent are two separate pieces.
The Kaminari kit has them as one big unit.
Modifying the stock vents is NOT the same thing as these vents.
The Aeroware vents physically stick out another 1" or so into the air stream more than the stockers.
I have the aerowares on Jekyl (actually I ahve 6 pieces of the 7-piece aeroware kit).
