Unfortunately I have no idea what the difference is highway mileage is between the skid and the air dam it had before. Like an idiot I neglected to find a long straight stretch of road to let my SGII show mileage at a constant speed. Then again, it's pretty hard without cruise control anyway.

All I do know is that my average mpg has stayed the same, 16-17.
