A buyer's guide to used Hyundai Ioniq catalytic converter
No two catalytic converters are quite the same across different vehicles, so getting the specifics right matters when you buy used, second hand or a replacement. Answer a few quick questions below and breakers will only quote if they have the exact matching part in stock:
- State whether it's petrol or diesel
- State the engine code if known

Fitment questions
Does the Hyundai Ioniq actually have a catalytic converter?
It depends on the variant. The Ioniq was sold in the UK in three drivetrain versions: a petrol-electric hybrid (1.6 GDi), a plug-in hybrid (PHEV, also 1.6 GDi), and a fully electric version (Ioniq Electric). The hybrid and plug-in hybrid variants do have a catalytic converter as part of their exhaust system, but the fully electric Ioniq has no combustion engine at all and therefore no exhaust system, catalytic converter, or DPF — if you own an Ioniq Electric, this part simply does not exist on your vehicle.
Will a catalytic converter from a 2017 Ioniq hybrid fit my 2019 Ioniq hybrid?
The Hyundai Ioniq (Mk1) ran from 2016 to 2022 in the UK, with a facelift arriving around 2019, so a 2017 car is pre-facelift and a 2019 is on or near that boundary. Both use the same 1.6 GDi hybrid engine code, which is a reasonable starting point, but whether the exhaust components interchange across the facelift boundary is exactly the kind of specific detail you need to confirm with the breaker against your registration before purchasing.
Does trim level affect which catalytic converter I need on the Ioniq hybrid?
No — trim level does not affect catalytic converter fitment on the Ioniq hybrid. The Ioniq was sold in UK trims including SE, SE Connect, Premium, and Premium SE, but all hybrid models share the same 1.6 GDi engine and exhaust configuration regardless of trim. What matters is the engine code, fuel type (hybrid vs PHEV), and the emissions standard the car was built to, not whether the car has heated seats or a larger infotainment screen.
Is the catalytic converter the same on the Ioniq hybrid and the Ioniq PHEV?
Both the standard hybrid and the plug-in hybrid use the 1.6 GDi petrol engine, so there is some mechanical commonality, but the exhaust systems may differ in detail between the two variants. Whether the catalytic converter itself is interchangeable between hybrid and PHEV is strong confirm-with-breaker territory — give the breaker both registration numbers and let them check the part numbers before you commit.
Do I need to worry about Euro 5 or Euro 6 when buying a used Ioniq catalytic converter?
Yes, this matters. The Ioniq hybrid launched in the UK in 2016, and emissions certification can affect which catalytic converter was fitted, as a converter built to a different emissions standard may not function correctly and could cause an MOT failure even if it physically fits. Always tell the breaker your registration so they can match the emissions era as well as the engine code — a visually similar converter from the wrong emissions generation is not a safe swap.
