MPV? Is this a good way to "boost" my fuel economy? Should I install one, or should I look into using two different sizes? I am also concerned about the whining. There's plenty of whining in my car already.
if you want to boost your fuel economy put a cold air intake on, it's a cheap easy thing to do, and most the time won't void any warranty you may have on your car (check, it's different from state to state).
It will give you a bit more power, better mileage.
