Hyundai Ioniq Exhaust Manifold Replacement Parts

This depends entirely on which Ioniq variant you have. The Ioniq Hybrid and Ioniq Plug-in Hybrid both use a 1.6-litre GDi petrol engine (engine code G4LE) which does have a conventional exhaust manifold. The Ioniq Electric, however, has no internal combustion engine at all, so there is no exhaust manifold — if you drive the fully electric version, this part simply does not exist on your car and you will not find one.

The Hyundai Ioniq ran from 2016 to 2022, with a facelift arriving for the 2019 model year. Both pre-facelift (2016–2018) and post-facelift (2019–2022) Hybrids and Plug-in Hybrids use the same 1.6-litre G4LE petrol engine, so the exhaust manifold itself may well carry across that boundary — but you should confirm the exact part number with the breaker against your registration before buying, as emissions-related components can differ between build dates even within the same engine code.

No, trim level makes no difference to exhaust manifold fitment on the Hyundai Ioniq. SE, Premium, and Premium SE trims all share the same 1.6-litre G4LE engine in Hybrid and Plug-in Hybrid form, so the manifold is identical across those grades. You only need to confirm your fuel type (Hybrid or Plug-in Hybrid) and engine code with the breaker — trim is irrelevant here.

Both the Ioniq Hybrid and Ioniq Plug-in Hybrid use the 1.6-litre G4LE petrol engine, so the exhaust manifold may be the same unit — however, the two drivetrains have different supporting hardware around the engine bay, and emissions calibration can vary. Confirm directly with the breaker using both vehicles' registrations to make sure the part from a Hybrid donor car is suitable for a Plug-in Hybrid application before committing to a purchase.

Potentially yes — while the exhaust manifold itself is not a direct emissions-control device, fitting one from a different emissions standard or specification can affect how cleanly the engine runs and how efficiently the catalytic converter downstream operates. A manifold that alters exhaust gas flow or temperature could cause the car to fall outside acceptable emissions limits at MOT. Always confirm the engine code and emissions specification of the donor car with the breaker matches your own vehicle before buying a used manifold.

The key thing to check is that the engine code on the donor car matches your own — for Hybrid and Plug-in Hybrid Ioniq models that should be the 1.6-litre G4LE. Give the breaker both your registration number and the registration of the car the manifold came from, and ask them to cross-reference the part numbers. Be aware that any associated catalytic converter hardware is strong confirm-with-breaker territory, as interchange specifics on emissions components vary and getting that wrong has MOT implications.
