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 4 plugs for a full set.
How often should I change spark plugs on a Hyundai i10?
Every 40,000 miles for iridium plugs. 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.
