So, thinking of getting the rear spoiler/wind deflector for my 2004. Just a little boring back there, however, the engineer in me sees a possible 'perk'....
Perhaps, redirecting the airflow into the turbulent area in the direct back of the vehicle could, slightly I know, reduce vacuum drag on her fat ass? I'm pushing 14MPG right now, but about to head to California and wanna squeeze her for the best I can get.
By vacuum drag, I mean the wind rushing off the top of the vehicle actually curls back on itself like an upside-down wave and creates an area of high pressure pulling backwards on square body vehicles.
*Would introducing a directed stream disrupt this drag effect?

What do you all think?
