It isn't negativity, it is logic.

Agree the stock filter flows more than the engine requires, and has the added advantages of not letting in additional dirt, and not letting in heated air from the engine compartment.

Advantages of the aftermarket air intake are underhood looks (for those that like it), increased intake noise (ditto), and in some cases washable filters (good for mudding with 4x4s, if you do that sort of thing in your X5)

All that said, people should do what they want with their own vehicles, they are personal statements.
