A CAI will help with fuel economy as long as your not hard on the throttle. If you drive in high RPMs you will need more fuel to keep up with the air. A short ram air will take in hot engine heat and not do much (unless the filter is over a wheel well with a heat shiled. If you want the performance the CAI will give you that and the economy if you lay off the threottle.
