Used Mazda CX-30 Cylinder Head

The engine code is the single most important detail — it tells a breaker exactly which cylinder head to match, far more reliably than the year or trim level alone. You'll find the engine code on your V5C logbook or via a VIN check. Supply this code alongside your fuel type (petrol or diesel) and gearbox type (manual or automatic) when requesting quotes, and breakers will be able to narrow down compatible units quickly. Never rely on year and badge alone for a mechanical part like a cylinder head.

The Mazda CX-30 launched in the UK in 2019 and received a mid-life update around 2022, so a 2020 car sits in the pre-update generation while a 2022 car may straddle or follow that revision. If the engine codes match between the two vehicles, the cylinder head is very likely compatible, but ancillary fittings and mounting details can change mid-production even within the same generation. You should confirm the exact interchange against your specific registration with the breaker before purchasing. Sharing both engine codes gives the breaker the clearest basis for comparison.

Trim level does not affect cylinder head fitment on the CX-30 — the head follows the engine, not the badge. A SE-L and a GT Sport running the same engine code will use the same cylinder head, so you don't need to match trim when sourcing the part. Bear in mind that a unit pulled from a higher-spec car may arrive with different ancillaries attached, such as sensors or covers, but the core head itself is determined by the engine. Strip or swap ancillaries as needed and focus your search on matching the engine code.

Yes, fuel type is fundamental — a petrol cylinder head and a diesel cylinder head are entirely different components and are not interchangeable under any circumstances. The CX-30 was sold in the UK with petrol engines including mild-hybrid variants, so make sure the unit you source matches your exact fuel type and engine code. When requesting quotes on Findapart, state your fuel type clearly alongside the engine code to avoid any confusion.

The cylinder head itself is attached to the engine block, not the gearbox, so gearbox type does not directly affect whether the head will physically fit. However, gearbox type can influence which engine variant was fitted — some engine and transmission combinations are specific to certain configurations — so it is worth supplying your gearbox type to the breaker alongside your engine code. This helps them verify the full engine spec matches and flag any ancillary differences that could affect installation.

If the engine codes are identical, there is a strong basis for compatibility, and engine code matching is the most reliable guide for a mechanical part like a cylinder head. That said, Mazda can introduce ancillary or mounting changes during a production run without changing the core engine code, and the CX-30 did receive updates during its production life. Confirm the interchange against both registrations with the breaker before committing to a purchase — they can cross-reference part numbers to check for any running changes.
