I took one frame and visually enhanced to show the air curtain vent:

Thanks to @Vekke who made the video that included this frame.

I found one paper about air curtains:

At $35, I'm not sure I want to buy it.

I did find these YouTube videos that offers insights:

Do you have a concern with wheel well, air curtains?

The reason I ask is I bought a polyethylene piece to block for the front air curtain inlets on my Model 3. My primary plan is to make a conformal cover for the slot outside of the front air inlet. I had also thought about testing blocking of the air curtain slots. But my wheel covers significantly reduce the amount of air leaking in/out of the spokes.

Guess I need to do some tuff testing.
