Important Compatibility

For an exact replacement, verify the VIN, engine serial number, BMW OEM part number and engine designation. The S63B44B/S63B44T2 specification for F85/F86 differs from the earlier S63 engines used in the E70/E71 X5 M/X6 M and from the S63B44T0 used in the F10 M5/F12/F13 M6.

Also confirm whether the engine is supplied with turbochargers, injectors, high-pressure fuel system, alternator, starter, wiring, intake/exhaust components and other ancillaries, as “complete engine” specifications vary by supplier.
