Modern airboxes make use of resonance to further assist filling the combustion chambers with air. Altering the size of the airbox and related tubing will affect the frequency it resonates at.

I'm not real familiar with your particular Civic, but a lot of modern airboxes I've seen have what's called a Helmholtz resonator on it, which helps to reduce noise and improve airflow at specific RPMs.

I don't have specifics on how you are supposed to size the airbox and/or Helmholtz resonator, so I can't help you there. I will need to build one for my race car project though, so it's something I need to get more info on.
