Second Hand Hyundai i20 Fuel Injector

Yes, fuel injectors exist on the Hyundai i20 across both petrol and diesel variants throughout its UK production run, so this is a genuine part for this model. However, the exact injector type varies significantly: direct-injection petrol engines use a different injector design and rail pressure to port-injection units, and diesel injectors are entirely different again. Always confirm your fuel type with the breaker, and treat petrol and diesel injectors as completely non-interchangeable.

These are different generations – the i20 Mk1 ran from 2008 to 2014, and the Mk2 launched in 2015 – so the platforms, wiring, and engine families differ substantially. Injector compatibility across this generation boundary is unlikely but ultimately depends on whether both cars share the same engine code, which you can find on your V5 or via a VIN check. Because ancillary and rail fitment details can also change at the generation boundary, confirm directly with the breaker against your registration before purchasing.

Trim level does not affect fuel injector fitment on the i20 – Classic, SE, and Premium are cosmetic and equipment distinctions that have no bearing on the engine or fuel system. What matters is that both vehicles share the same engine code and fuel type, which the breaker can verify against your registration. You may find minor cosmetic differences on ancillary brackets or covers depending on the donor car, but the injector itself is determined entirely by the engine, not the badge.

The engine code matters far more than the year, because Hyundai offered multiple different petrol and diesel engines across the same model years of the i20. Two cars built in the same year could carry entirely different injectors if they have different engine codes. Your engine code is printed on your V5 logbook or can be confirmed through a VIN check, and supplying it to the breaker is the single most useful thing you can do to ensure you get the correct part.

The Mk2 i20 received a facelift around 2018, so a 2017 car sits in the pre-facelift Mk2 range that launched in 2015. Whether injector specification changed at the facelift point depends on the specific engine code, and mid-production ancillary or mounting changes are something you should confirm with the breaker against your registration rather than assume. Providing your engine code alongside your registration gives the breaker the best chance of matching the correct injector.

Fuel injectors on some i20 engines do require the injector trim codes to be programmed into the ECU after fitting, and whether pairing or coding to your specific vehicle is needed is something you must confirm with the breaker and your fitting garage rather than assume. This does not mean a used injector cannot be fitted, but it does mean the job may require a diagnostic tool beyond a straightforward swap. Your fitting garage will be able to advise on whether coding is required for your specific engine variant.
