I was not vouching for the study. The OP mentioned it. I was curious. I am not willing to assume it means they work, either. Anyway, my understanding it that the Evo design's airtab placement took a lot of windtunnel time. I imagine micro adjustments matter a lot.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
