This number superseded the earlier 63-12-8-350-144. BMW marks the change as exchangeable retrospectively, so the current screw also fits cars that were built with the older one. The same part covers a wide range of engines. On the E34 5 Series, these include the M20, M50, M30, and M60 gasoline engines, plus the S38 in the M5. On the E32 7 Series, they include the M30, M60, and M70 V12.
