Frequently Asked Questions
- What spark plugs does a Ford Fiesta use?
- The Ford Fiesta spark plug type varies by year and engine. Newer models (2010+) typically use iridium plugs for longer service life. Older models may use platinum or copper. Check the specs below for your exact year.
- How often should I change spark plugs on a Ford Fiesta?
- Modern Ford Fiesta models with iridium plugs can go 60,000-100,000 miles between changes. Older models with copper plugs need replacement every 30,000 miles. Replace sooner if you notice misfires, rough idle, or poor fuel economy.
- What is the spark plug gap for a Ford Fiesta?
- Most Ford Fiesta models use a spark plug gap between 0.039" and 0.044" (1.0-1.1mm). Pre-gapped plugs from the OEM are recommended. Do not re-gap iridium-tip plugs as it can damage the electrode.
- Can I upgrade to iridium spark plugs in my Ford Fiesta?
- Yes, upgrading from copper or platinum to iridium is generally safe and beneficial. Iridium plugs offer better ignitability, longer life, and improved fuel economy. Just match the correct heat range and gap for your engine.
