Not correct for US spec cars. The BMW performance intake re-uses half of the stock airbox. The filter is the same shape as the stock paper filter except the performance intake kit comes with a K&N oiled filter instead of a dry paper one. The charcoal filter is still used, so if you don't want it, you must cut it out.
