Cold Air Intake - Cover on or Cover off?

I have a Volant Cool Air Intake and have been running it with the cover off due to this setup:


I want to try running with the cover on due to the filter getting crazy dirty but I guess I dont understand how that will be a better option. There is an opening in the box on the passenger side but it won't get alot of airflow due to being right against the panel, then there is a panel in the front with a rubber boot on it...

Any thoughts? Need pics?

 

ya stocks is through the fender. there was also a thread saying that there is very minimal air flow around the hood scoop area which is why i am a little suprised that you did something incorperating it....but hell your setup is fucking sick as shit looking!

 

I know you said the filter gets "crazy dirty" but does water get into the CAI?
