Cheap BMW i4 Cylinder Head

The BMW i4 launched in 2022 and is currently in its first generation, so a 2022 and a 2024 car share the same generation platform — however, the engine code (visible on your V5 or via a VIN check) is the detail that really drives cylinder head fitment, not the model year alone. Match the engine code exactly before assuming a cross-year swap will work, and confirm with the breaker against your registration whether any ancillary or mounting changes were introduced mid-production. Never assume fitment on year alone.

The i4 eDrive40 and i4 M50 use different electric drive units and, critically, different engine codes, so the cylinder head from one will not simply cross over to the other — mechanical parts follow the engine code, not the badge or trim name. Confirm the exact engine code from your V5 or a VIN check and supply that to the breaker, as this is the single most reliable way to identify the correct part. Do not assume fitment based on the i4 nameplate alone.

Trim level — whether your car is a standard i4 eDrive40, an M Sport, or an M50 — does not in itself determine cylinder head fitment; what matters is the engine code, which can be the same across different trim grades built around the same drive unit. You may find cosmetic differences between donor cars (interior spec, alloy style, exterior trim), but these are irrelevant to whether the cylinder head will fit your engine. Always match on engine code, confirmed against your registration.

No — the BMW i4 is a fully battery-electric vehicle and its drive unit is fundamentally different from any internal combustion engine; a petrol or diesel cylinder head from another BMW is entirely the wrong part and will not fit. When searching for a used i4 cylinder head, make sure the breaker is supplying a part from an electric i4 donor car with a matching engine code. Confirm the exact code with the breaker against your registration before purchasing.

The most reliable step is to find your engine code — it appears on your V5 logbook or can be retrieved via a VIN check — and give that code directly to the breaker rather than relying on year or model name alone. Year within the generation is a useful secondary check, but ancillary fittings and mounting details can change mid-production, so always confirm those specifics with the breaker against your exact registration. No online guide can guarantee fitment; that confirmation sits with the breaker who has the physical part in front of them.

If the engine code on the donor part matches the engine code on your car exactly, that is a strong indicator of compatibility within the same first-generation i4 range (2022 onwards). However, confirm with the breaker that no ancillary or mounting changes were introduced between the 2022 and 2023 build dates, as these details can shift quietly mid-production run. Matching engine codes is the starting point, not the final guarantee.
