So I can do this for you...

1) Put back on that stock air-vent. CAI will do nothing for you but add noise and chance of hydrolocking your engine if you suck up water, unless you have a water bypass or something
2) You want power? Turbo or swap. Intake/headers/exhaust are only for sound.
Remember.... the basic trim Civics are a city/family car not a performance/sports vehicle, you'll have to do a lot more to get power.
