It's probably not worth it mate. The stock filters are decent enough. However, if you want a little more noise, get on the case with a Ram or Cold Air Open Element Intake.
Just wanted slightly better airflow, I have got one on my 6th gen and have no complaints after 16000 miles.
Was easy to clean where as if it was oem I would have replaced it by now.
If it's a diesel you're asking about, then the stock filter and box is the best... a guy on the Civinfo forum performed a whole bunch of tests to prove this.
