The stock air box is pretty efficient, to be honest. Unless if you're chasing the cone filter/cold air intake noise, a drop-in filter is basically all you need. Chances are the MAF scaling for the new intake is different, so it may require a tune. As far as I know, only a few aftermarket CAIs are close to the factory MAF scale. The Grimmspeed one comes to mind. If you have a datalogger you can compare commanded AFR to actual AFR to get an idea of how far off the scaling is.
