I really disagree about air tabs being put in the unicorn coral. They have been tested a proven to work on a car to show drag reduction that will result in measurable gains in FE. You do need a PHD and a wind tunnel to do it right though.
Just because they won't work on all cars and is beyond the abilities of anybody here to get it right does not mean it should be listed with shams like acetone and HHO.
