Improving 2008 Focus Sedan Aerodynamics

I regularly travel 120 miles every other week averaging 65 mph. I am looking at different ways to improve mpg. I currently run around 34mpg at 85mph and 36mpg at 75mph. I am planning to get a fswerks CAI for a bit of a boost, but have started to consider some kind of aero kit. I decided to try drafting on my trip today and found that I could get 38mpg as I was following a HD3500 at 80mph. This led me to ask, what kind of drag do these cars have stock and what can I do to help reduce the amount of drag at high speeds? Are there any beneficial aftermarket kits or will I have to do custom fab? I tried to find a previous thread for this and could not so I decided to start one. If anybody can impart some wisdom or point me in the right direction any help will be appreciated.

Oh yah, specs
