When should I change out my Ford Kuga's spark plugs?

I recently bought a Ford Kuga and I'm wondering when I should change out the spark plugs. They seem to be working fine now, but how often should I replace them to keep my car running smoothly?

It's recommended to change your spark plugs every 30,000 miles or 3 years, whichever comes first. However, if you notice any issues with your car's performance, like difficulty starting or decreased fuel efficiency, it may be a sign that your spark plugs need to be replaced sooner.

I change my Ford Kuga's spark plugs every 50,000 miles and have never had any issues. It's always better to err on the side of caution and replace them earlier rather than later. Plus, it's a relatively inexpensive maintenance task that can greatly improve your car's performance.
