The exact spark plugs for a Hyundai i20 depend on the engine, because the i20 has been sold with several petrol engines over different generations. Here are the most common ones so you can identify yours.
1.2L petrol (Kappa / G4LA engine)
Very common in i20 models from around 2009 onward. Typical plugs include:
- NGK LZK6RB-10E
- Champion RER8MC
- Bosch YR7ME
These plugs usually have M12×1.25 thread and about 26.5 mm reach, with a typical gap around 0.8–1.0 mm.
1.4L petrol (Gamma / G4FA or G4LC engines)
Often uses plugs such as:
- NGK LZKR6B-10E
- Denso ZXU20HPR11 or similar equivalents.
1.6L petrol (some markets)
Usually the same style as the 1.4 Gamma engine plugs (NGK or Denso equivalents with similar thread and heat range).
1.0T / 1.4T turbo engines (newer i20 generations)
These typically use iridium plugs, such as NGK ILKR-series plugs designed for turbo Hyundai engines.
That said, if you want the exact plug part number, torque spec, and replacement procedure, the service & repair manual usually lists the correct plug code for each engine, electrode gap, tightening torque, and step-by-step replacement procedure.
Perhaps you could reach out to us again with your i20 model year and engine so we can assist you further ✌🏻
