It may be a bit faster of an interface, but some vehicles need to use the yellow head and some need the OPPS head. The E53 happens to need the yellow one. The OPPS head has the fiber optic interface for programming the MOST bus on newer vehicles with the fiber optic audio bus system. The OPPS head is pretty much useless for the E53.
