Frequently Asked Questions
What spark plugs does a Hyundai i10 use?
The Hyundai i10 (Mk3) uses NGK SILZKR7B-11 iridium spark plugs. The gap should be set to 1.1 mm. You need 3 plugs on the 1.0 MPI three-cylinder engine (4 on the 1.2 MPI).
How often should I change spark plugs on a Hyundai i10?
Per the Hyundai service schedule — iridium plugs typically last longer than this. Iridium and double iridium plugs last longer than standard copper or nickel plugs.
Can I use a different brand of spark plug in my Hyundai i10?
Yes, as long as it matches the exact specification — same heat range, thread size, reach, and gap (1.1 mm). NGK SILZKR7B-11 from any major manufacturer (NGK, Denso, Bosch, Champion) will work.
What are the signs of worn spark plugs?
Rough idle, poor fuel economy, hesitation during acceleration, engine misfires, and difficulty starting. If your engine management light comes on with a misfire code, spark plugs are a common culprit.
How we check fitment for this guide
We cross-reference fitment figures against manufacturer specifications and OE-supplier catalogue data where available, and matched to the standard codes that actually govern fit — battery type/group sizes, wiper lengths and fitting types, bulb fitment codes, tyre size markings, and oil specifications. We work by make, model, year, engine, and build date, because a single model can take different parts across its life. Where the right part depends on your exact vehicle, we tell you to confirm by registration or VIN. More on our method →
