BMW shares this one socket number between two model lines. On the E34 it covers the M50 and M60 cars sold here as the 525i and 530i. On the E32 it covers the M30 735i and 735iL, the M60 740i and 740iL, and the M70 750iL. Because one part serves both chassis, an owner running a 5 Series and a 7 Series from this era can stock a single spare.
