How often should I replace my Ford EcoSport's spark plugs?

I just bought a used Ford EcoSport and I'm not sure when I should replace the spark plugs. What's the recommended interval for spark plug replacement in a Ford EcoSport and how can I tell if they need to be replaced? Any tips for maintaining the spark plugs and extending their lifespan?

Generally, spark plugs should be replaced every 30,000 miles or every 3 years, whichever comes first. However, it's always best to check your owner's manual for the specific recommendation for your Ford EcoSport model. As for how to tell when they need to be replaced, look for signs of wear and tear or misfires in the engine.

To maintain your spark plugs and extend their lifespan, make sure to regularly inspect and clean them, as well as use high-quality fuel to prevent build-up. Also, be aware of any changes in your engine's performance or fuel efficiency as these can also indicate when the spark plugs need to be replaced.
