Put the standard airbox back in with a good panel filter.
And I'm serious, pods increase induction noise so if you're not happy with it, go back to the airbox, get a CAI for it and put a good filter in.
You'll probably notice better results with the airbox, cause the pod filter sucks in hot air from the engine bat at the lights and the airbox with a CAI sucks coolver air from outside.
Your other, more expensive option is to get an enclosure for the pod filter. There are a few comapnies that make these or if you have the skills you can try to make one yourself.
Check out the MACE site in regards to one of these.
EDIT:
Move thread to more appropriate section.
