That equates to $1.72 less per fillup at local prices.

I searched around until I found a picture of your airdam..
I'm pretty sure that I've never seen one with that kind of frontal coverage.
I don't know very much about aero mods, but looking at that airdam,
I would have guessed that it would have been more effective.
A gain of 0.66 MPG is ok, but it just seems logical that it would have been greater.

So, I have to ask.. How draggy does your stock underbody look?

Thanks,
