From the manual (see below for spark plugs), for all X series BMWs except Diesel or real M (i.e.: X6 M).

As for transmission and Differential oil, unless it is a formal M vehicle "which is not", the oil is "lifetime" according to BMW. If you keep your vehicles for 200K miles, change at ~100K miles if you really have to, otherwise u r just wasting your money. No measurable benefits at all for the real risk.
