Most aftermarket CAI's will have the same filtering capability.
I doubt you would see any gains with a CAI. It's a great supporting mod if you decide to turn up the wick with larger injectors and/or programming. Allowing more air into the engine will keep the EGT's manageable.
EGT = Exhaust Gas Temps.
Same thing goes for the exhaust if you are planning one of those too.
