Frequently Asked Questions
What spark plugs does a Renault Clio use?
The Renault Clio (Mk5) uses NGK LZKAR6AP-11 platinum 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 Renault Clio?
Every 30,000 miles for platinum 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 Renault Clio?
Yes, as long as it matches the exact specification — same heat range, thread size, reach, and gap (1.1 mm). NGK LZKAR6AP-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.
