Is It Necessary to Change the Spark Plugs on My Ford Fiesta?

I have a Ford Fiesta that is about 5 years old. Recently, I've noticed that my car is not running as smoothly as it used to. I've heard that changing the spark plugs can improve performance, but do I really need to change them? Can it be done without professional help?

Yes, it is recommended to change the spark plugs on your Ford Fiesta every 30,000 miles or every 3-4 years, whichever comes first. Although your car may still be running, old spark plugs can cause misfires, decrease fuel efficiency, and even damage your engine in the long run.

Changing the spark plugs is not a difficult task and can be done at home if you have the right tools and follow the proper steps. Just be sure to consult your car's manual and watch some instructional videos online to ensure you do it correctly.

I've been driving a Ford Fiesta for years and have always changed the spark plugs regularly. Trust me, it's worth the investment to keep your car running smoothly and efficiently.
