Frequently Asked Questions
What spark plugs does a Vauxhall Corsa use?
The Vauxhall Corsa (Mk5/F) uses NGK LZKR6AI-10G platinum spark plugs. The gap should be set to 0.8 mm. You need 3 plugs (the 1.2 PureTech is a 3-cylinder engine).
How often should I change spark plugs on a Vauxhall Corsa?
Every 40,000 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 Vauxhall Corsa?
Yes, as long as it matches the exact specification — same heat range, thread size, reach, and gap (0.8 mm). NGK LZKR6AI-10G 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 →
