Personally I wouldn't put an open induction kit on these cars, engine compartment must get pretty hot. There are some induction kits around but these all tend have the filter quite low down near the bumper (e.g. forge) but are not advised in very wet conditions.
Carbonio intake you can't go wrong with, looks good and seems to do the job better than the OEM bit of plastic.
If its on stock suspension then yes ideally it does need a slight drop
