Buying a used BMW Z4 cylinder head: what matters
Fitment on a used cylinder head varies by vehicle, so a bit of detail goes a long way. Our request form covers what breakers need to know, so every quote you get back is for the correct part:
- State whether it's petrol or diesel
- State the engine code if known

Fitment questions
What engine code do I need to find a matching cylinder head for my BMW Z4?
The engine code is the single most useful detail you can supply — it determines which cylinder head fits, far more reliably than the year or badge alone. You'll find the engine code on your V5 logbook or via a VIN check. Give the engine code to the breaker and they can match a head directly rather than working backwards from the registration.
Does a cylinder head from an E85/E86 Z4 (2003–2009) fit the later F20-based G29 Z4 (2018–present)?
These are entirely different generations with completely different engine families, so a cylinder head from the E85/E86 Z4 (2003–2009) will not cross over to the G29 Z4 (2018–present). The G29 uses BMW's B48 and B58 turbocharged petrol units, while the E85/E86 used older M54, N46, and N52 units among others — none of which share a cylinder head design. Always confirm against your engine code with the breaker.
Will a cylinder head from a 2006 Z4 fit my 2008 Z4 — they're both E85 generation?
Both fall within the E85/E86 generation (2003–2009), so fitment is possible if the engine codes match, but BMW made running production changes during that period that can affect ancillary fittings and porting. Match the engine code first, then confirm with the breaker against your registration that no mid-run changes affect the specific head you're buying. Never assume year-to-year compatibility without that check.
Does the trim level — for example Z4 SE versus Z4 Sport or Z4 sDrive20i versus sDrive30i — affect which cylinder head I need?
Trim level alone does not affect cylinder head fitment — the head follows the engine, not the badge or specification level. What does matter is whether different trims or sub-models were fitted with different engines; for example, an sDrive20i and an sDrive30i carry different engine codes and will need different heads. Identify your engine code from the V5 or a VIN check and supply that to the breaker rather than relying on trim name.
I've found a cylinder head from a petrol Z4 — will it fit my diesel Z4?
No — petrol and diesel cylinder heads are fundamentally different in design, combustion chamber layout, and injector configuration, and they are not interchangeable under any circumstances. Check your V5 to confirm your fuel type and engine code before approaching a breaker. Always supply both the fuel type and the full engine code so the breaker can pull the correct head.
Does the gearbox type — manual or automatic — affect which cylinder head fits my Z4?
The gearbox type does not directly determine which cylinder head you need, as the head is part of the engine assembly rather than the drivetrain. However, some engine variants were paired exclusively with certain gearboxes, so your engine code remains the definitive guide. Confirm the engine code with the breaker and mention your gearbox type as a secondary detail so they can sense-check the combination.
