About Spark Plugs
What do they do?
Spark plugs ignite the air-fuel mixture in petrol engines. They fire thousands of times per minute and endure extreme heat and pressure. Diesel engines don't use spark plugs — they use glow plugs for cold starting.
When to replace
Standard copper plugs last 20,000–30,000 miles. Iridium and platinum plugs last 60,000–100,000 miles. Signs of worn plugs include rough idle, misfires, poor fuel economy, and difficulty starting.
Brand guide
NGK and Denso supply spark plugs to most car manufacturers as OEM. Bosch is also widely used. Always match the exact plug specification (heat range, gap, thread size) for your engine.
💡 Top tip: When buying spark plugs, your vehicle registration lookup will give you the exact specification. Using the wrong heat range or gap can cause misfires, detonation, or even engine damage.
