How often should I replace the spark plugs in my Kia Picanto?

I have a 2018 Kia Picanto and I'm wondering how often I should replace the spark plugs in order to maintain optimal performance. Can you provide some advice on when to replace them and any signs that indicate they need to be replaced?

It's recommended to replace your spark plugs every 30,000 miles or according to your vehicle's manufacturer guidelines. However, if you notice any decrease in engine performance or difficulty starting your car, it's best to have them inspected and replaced if necessary.

I own a Kia Picanto as well and I typically replace my spark plugs every 2 years. However, it's always a good idea to check your owner's manual for specific recommendations.

If you notice your engine is misfiring or your fuel economy has decreased, those are signs that your spark plugs may need to be replaced. It's also a good idea to inspect them for any wear and tear to determine if they need to be changed.
