BMW M4 Cylinder Head Replacement Parts

The BMW M4 was introduced in 2014 as an F82 generation model, with the current G82 generation arriving in 2021 — these are completely different engines, so a cylinder head from the F82 will not fit a G82. Even within the F82 generation (2014–2020), confirm the exact engine code with the breaker against your registration, as ancillary and mounting details can vary across the production run. The engine code, found on your V5 or via a VIN check, is the single most important detail to supply.

Both the 2017 and 2020 M4 fall within the F82 generation (2014–2020), which used the S55 straight-six twin-turbo engine, so they share the same engine family. That said, confirm the precise engine code from your V5 with the breaker, as ancillary and mounting changes can occur mid-production without a formal facelift. Never assume fitment is guaranteed without the breaker cross-referencing your registration.

No — 2019 falls within the F82 generation (2014–2020) using the S55 engine, while the 2021 G82 uses the newer S58 engine, making these heads incompatible. This is a generation boundary where the engine changed entirely, so there is no crossover in cylinder head fitment. Always supply your engine code to the breaker to confirm the correct part.

The Competition trim on the M4 shares the same S55 engine (F82 generation) or S58 engine (G82 generation) as the standard M4 — trim level does not affect cylinder head fitment. You may find ancillary differences depending on the exact build, so it is worth confirming with the breaker against your registration, but the head itself follows the engine code rather than the Competition badge. Cosmetic or interior differences between trim levels are irrelevant to this part.

The engine code is the single most useful detail you can supply — for the F82 generation M4 (2014–2020) this is the S55 straight-six twin-turbo, and for the G82 generation (2021 onwards) it is the S58. You can find the engine code on your V5 logbook or by running a VIN check, and giving this directly to the breaker will allow them to confirm compatibility far more reliably than quoting the year alone. Fuel type and gearbox type are also worth mentioning, though the M4 has always been petrol.

The cylinder head itself is a mechanical component, but confirm with the breaker against your registration whether any sensors or ancillaries supplied with the head may require coding to your vehicle. BMW engine management systems can be sensitive to component changes, so it is sensible to discuss this with your fitting garage or specialist before purchasing. This is something the breaker or a BMW-specialist workshop is best placed to advise on for your specific registration.
