Used Hyundai Ioniq Cylinder Head

The Hyundai Ioniq was produced from 2016 onwards, with a facelift arriving for the 2019 model year, so a 2018 head and a 2020 head sit either side of that facelift boundary. The engine code is the single most reliable guide here — if both cars share the same engine code (found on your V5 or via a VIN check), the internal architecture is likely the same, but confirm with the breaker whether any ancillary or mounting changes were introduced at the facelift that could affect your specific build.

Yes — the Ioniq Electric uses a purely battery-electric drivetrain and does not have a combustion cylinder head at all, so this part only applies to the Hybrid and Plug-in Hybrid variants. Within those, always match on engine code first; supply your fuel type and gearbox type to the breaker so they can pull the correct head for your exact application.

Trim level has no bearing on cylinder head fitment — SE, Premium, and Premium SE are badge and equipment differences, not mechanical ones. The engine in all three is the same unit for a given fuel type and year, so a head from any of those trims will be mechanically equivalent provided the engine codes match. You may receive a head with different ancillary brackets or sensors depending on the donor car's spec, so confirm any ancillary details with the breaker against your registration.

The original Ioniq generation ran from 2016, with the facelift introduced for the 2019 model year, so a 2017 car is pre-facelift. The core engine code should be your primary check; if the head from a post-2019 car carries the same code, the core fitment may well be fine, but whether any mid-run ancillary or mounting changes affect your specific build is something to confirm with the breaker against your registration rather than assume.

The most important detail is your engine code, which you can find on your V5 logbook or by running a VIN check — this tells the breaker far more than the year or trim alone. You should also provide your fuel type (hybrid or plug-in hybrid), gearbox type, and model year so they can cross-reference their stock accurately. Never rely on year and trim name alone, as engine codes are the definitive guide for a mechanical component like a cylinder head.

Both the standard Hybrid and the Plug-in Hybrid use a combustion engine, and if the engine codes match the head itself may be compatible, but confirm this with the breaker before purchasing. Gearbox type can differ between the two variants and while that does not directly affect the cylinder head, it is worth providing your full spec so the breaker can verify the donor car is a true match for your application.
