Frequently Asked Questions
What spark plugs does a Suzuki Vitara use?
The Suzuki Vitara (Mk4 FL) uses NGK DILKAR6A-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 Suzuki Vitara?
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 Suzuki Vitara?
Yes, as long as it matches the exact specification — same heat range, thread size, reach, and gap (1.1 mm). NGK DILKAR6A-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.
