BMW M2 Cylinder Head Replacement Parts

The engine code is the single most important detail for sourcing a used cylinder head — it determines compatibility far more reliably than the year or badge alone. On the M2 F87 (2016–2021) you're looking at the S55 straight-six, while the M2 Competition (from 2018) uses the same S55 but with revised tune, and the M2 CS uses the same block family again. Check your V5 or run a VIN check to confirm your exact engine code before approaching a breaker, and quote it directly when requesting a quote on Findapart.

Both the standard M2 F87 (2016–2018) and the M2 Competition (2018–2021) use the S55 engine, so they share the same engine family across that production run. However, the Competition arrived with revised engine internals and ancillary changes, and whether a head from a pre-Competition car crosses that boundary without issue is something you should confirm with the breaker against your specific registration and engine code. Never assume fitment across a trim or spec change without the breaker verifying part numbers.

In terms of trim level, the M2 and M2 Competition are not differentiated by body style or cosmetic spec — the cylinder head fitment is governed by the engine code, not the Competition badge itself. Both variants use the S55 engine family across the F87 generation (2016–2021), but confirm your exact engine code with a VIN check and quote it to the breaker, as ancillary or casting differences between build dates should be verified against your registration rather than assumed.

No — the G87 M2 (2023 onwards) uses the S58 engine, while the F87 M2 (2016–2021) uses the S55, and these are entirely different engine families with no cylinder head interchangeability. Always match the head to your exact engine code; fitting a head from the wrong generation is not compatible and a breaker will tell you the same. Quote your engine code and registration when requesting a quote on Findapart.

No, the gearbox choice does not affect cylinder head fitment; the head is matched to the engine, not the transmission. The F87 M2 was offered with both a six-speed manual and a seven-speed DCT, but both used the S55 engine, so the head specification is the same regardless of which gearbox your car has. Quote your engine code to the breaker and you can ignore the gearbox when sourcing this part.

Beyond confirming the engine code matches yours exactly, ask the breaker whether the head has been pressure-tested or inspected for cracks, and whether it comes with camshafts or valvetrain components, as these are often stripped separately on S55 engines. ECU pairing and immobiliser coding are separate concerns from the head itself, but confirm with your fitting garage whether any coding work will be needed once the head is installed. A reputable breaker on Findapart should be able to tell you the mileage and condition of the donor vehicle.
