How often should I replace my Kia Picanto's spark plugs?

I've noticed my Kia Picanto has been losing power and not running as smoothly as before. I suspect it may be time to replace the spark plugs, but I'm not sure how often this should be done. Can you provide some advice?

Spark plugs should typically be replaced every 30,000 miles or 3 years, whichever comes first. However, if you notice a decrease in performance or fuel efficiency, it may be necessary to replace them sooner.

It's always a good idea to follow your Kia Picanto's maintenance schedule. Check your owner's manual for the recommended interval for spark plug replacement.

If you're experiencing decreased power and rough engine performance, it's likely your spark plugs need to be replaced. Don't wait too long to replace them as it can lead to further damage.
