How often should I replace the spark plugs on my Ford Mondeo?

I've been experiencing a bit of hesitation and rough idling lately in my Ford Mondeo. I'm thinking it might be time to replace the spark plugs. How often should I do this?

It's generally recommended to replace spark plugs every 30,000 miles or every 5 years, whichever comes first. However, if you're experiencing issues like hesitation and rough idling, it's best to do it sooner rather than later.

I suggest checking your owner's manual for the recommended maintenance schedule for your specific Ford Mondeo model. It's always best to follow the manufacturer's recommendations.
