Mercedes-AMG GLC 63 Complete Engine M177 – OEM AMG Biturbo V8

Mercedes-AMG GLC 63 complete engine, this genuine OEM M177 4.0-litre V8 biturbo powertrain is the direct, factory-correct replacement engineered to restore full AMG performance.

Every Mercedes-AMG GLC 63 complete engine unit is sourced from a donor vehicle, tested, and verified before shipping — giving you a true drop-in solution without the gamble of a rebuilt or aftermarket block.
