I have a Honda Civic EX 2002 Sedan. What would be the most cost effective add-on, besides driving habits, which would give me the best mpg? Like someone mentioned, I drive between 500-700 miles a week! I do drive easy but also use my air quite a bit, even around town in the summer. I wear a shirt and tie so I have to unless I want to smell all day! Anyway, should I look into air intake first or something else? BTW, how much we talking here I need to spend?? I'm sure driving as many miles as I do it would pay for itself over time.
Can someone suggest what I should look into or add? Is this something I can possibly do myself? Hmmm...
Later!
