Anybody have any insight on the Banks/Volant or any other Ram Air kit? Would it be any better then a regular CAI?

Currently this is my situation. I have a True Flow CAI, nothing special and not the XDI series (I wish). However, to the best of my knowledge True Flow fell under with the recession. Bummer, cause I really liked there setups. Anyways, right now I just have the intake tube, that goes into the stock filter housing with a true flow filter. Now, I know I could just buy a K&N filter and be good to go (I can't find any cleaning kits for my current filter). However, would there be any performance gain to put in a whole new CAI or is my setup good enuf? Ram Air add any benifts? I want more power, and I'm getting sick of the stock filter housing... Anyways any ideas would be great !!
