Used Hyundai Kona Catalytic Converter

Yes, all petrol-engined Kona models have a catalytic converter as part of the exhaust system. The diesel variants use a different emissions setup centred on a DPF and SCR system rather than a traditional standalone cat, though a catalytic element is still present. If you are unsure which setup applies to your car, check your V5C for the fuel type and confirm the exact configuration with the breaker against your registration.

The Hyundai Kona first generation ran from 2017 to 2023, with a facelift arriving in 2021, so both years sit within the same generation. However, the facelift brought some engineering updates, and whether a pre-facelift cat crosses over to a post-2021 car depends on the engine code and emissions specification of both vehicles. Name the generation boundary confidently but treat the actual part interchange across it as confirm-with-breaker territory — give the breaker your registration and ask them to match engine codes before buying.

Trim level does not affect catalytic converter fitment on the Hyundai Kona — the cat follows the engine and emissions specification, not whether the car has leather seats or a sunroof. An SE, Premium, Ultimate, or N Line car with the same engine code and the same emissions standard will use the same cat. Do bear in mind that a used unit may look slightly different cosmetically depending on its age or supplier, but the fitment criteria are engine code and Euro emissions era, not trim.

These are two different petrol engines with different engine codes, and they are very unlikely to share the same catalytic converter — the exhaust systems are engineered to match each specific engine's output and emissions targets. Always identify which engine code is fitted to your car before sourcing a used cat, and give the breaker both your registration and the engine code so they can match it accurately. Never assume a cat from a different engine variant will fit or pass MOT, even if the cars look identical from the outside.

No — petrol and diesel exhaust systems are fundamentally different and the parts are not interchangeable. A petrol Kona uses a conventional three-way catalytic converter, while a diesel Kona's emissions hardware is built around a diesel particulate filter and selective catalytic reduction system designed for diesel exhaust chemistry. Always confirm your fuel type with the breaker and make sure they are supplying a unit matched to a petrol car with the same engine code as yours.

The key things to confirm are your engine code (found on your V5C or stamped on the engine), your fuel type, and the emissions standard your car was built to, as Euro 6 rules apply to Kona models from around 2017 onwards but there can be variation between early and later builds. A visually similar cat from the wrong emissions era may not fit correctly or could cause your car to fail its MOT. Confirm all of these details against your registration with the breaker before purchasing, as catalytic converter interchange specifics are strong confirm-with-breaker territory.
