Applications

• BMW M3 F80
• BMW M4 F82 Coupe
• BMW M4 F83 Convertible
• Selected later S55 applications, including Competition, CS and GTS variants, use higher-output calibrations.

The standard 431-PS version uses the S55’s 3.0L inline-six, two mono-scroll turbochargers, direct injection, VALVETRONIC and Double VANOS.

Important Compatibility

The 20,000 km mileage makes this a particularly attractive low-mileage replacement engine, but verify the exact engine specification before installation. S55 variants can produce 431, 450 or higher outputs, with differences in ECU calibration and supporting components.

Confirm:

• VIN
• Exact engine number
• BMW OEM part number
• Standard vs. Competition/CS/GTS specification
• ECU/DME
• Turbochargers
• Wiring and sensors
• Ancillary components
• Cooling and oil systems
