Gasoline Fumes — Thanks for reposting that. Times past I've wasted whole minutes in Google's search function trying to find an example.

I think it's a good [possibly extreme] example of a central jet. There seems to be advantage to having most of the air under the car being sucked into the center. (Away from the wheels/tires?)

The way I see to improve it would be to have the deflectors twice as tall, up to the parking light, and vented to provide an air curtain over the front wheels.

As to the question at hand, they do work. They control the stagnation point if they are even with the body, and add downforce if they protrude ahead of the body.
