MetroMPG - You mentioned an air dam in the original post.

Can you (or trebuchet03 or anyone else for that matter) expand on that some, provide some detail on why it works?

I've seen some posts on non-FE sites, saying that an air dam will increase drag and reduce FE. I say that's likely true if the air dam is designed to create downforce. I'm pretty convinced of the FE value of an air dam that's designed for FE, especially if a belly pan is included to seal off the gap. But it would be good to see some more detailed analysis.

Thanks in advance.
