AIR TABS and my lying eyes, you gotta read this!

To me the air tab looks like a Naca scoop or inlet which have been around longer than me. I have seen them on a lot of A/C. We even used them on Sikorsky helicopters. They are used primarily in inlets and reduce pumping loses on intakes at low speeds like 120 mph for a helicopter, but can really improve the air pressure by 50 pct for a fixed wing A/C. Several on here have posted modest improvements using these, maybe they will post their results.
