Search for areos for my 04 Focus ZX3....

[TheWildHippie]

So I have my new to me Focus in the 40mpg range when I take it REAL easy, but I want to mod it with a few areos to keep it at least in the 32~35mpg range under "normal" driving conditions. Right now, when I drive it like I consider "normal" I get only about 30......Any Focus ZX3 owners here with tips like how to on the garage door front dam or any CARB EPA legal motor mods?

2004, ZX3 3 door hatch, all stock, Zetec 2.0, 5 speed.
