How often should I change the spark plugs in my Ford Ranger?

I just bought a Ford Ranger and wanted to know how often I should change the spark plugs? I've heard conflicting answers and want to ensure I'm taking proper car of my vehicle.

It's recommended to change the spark plugs every 30,000 miles or every 3-5 years, whichever comes first. You can consult your Ford Ranger's owner's manual for specific guidelines.

If you're experiencing rough idling or difficulty starting your car, it's a good idea to check and potentially replace your spark plugs.

A general rule of thumb is to replace your spark plugs every 100,000 miles. However, it's always best to follow the manufacturer's recommendations for your specific vehicle.
