If you don't use your AC, just remove it. That's what I'm going to do for mine, but of course mines not working anyway, and requires a conversion.
You can get a k&n typhoon intake for around $142. I'm sure apc makes cheaper crap though.
Get a fuel injection service done. they run about $50 and they clean out your injectors and whatnot of carbon deposits. If 50 is too rich for you go to autozone of something and pick up that STP injector cleaner.
