How often do I need to change my Kia Ceed's spark plugs?

I recently bought a Kia Ceed and I'm not sure about the recommended interval for changing spark plugs. Can you give me some advice on when is the optimal time to change them and what kind of spark plugs are best for my car?

In general, it's recommended to change your Kia Ceed's spark plugs every 30,000 miles or every 3 years.

As for the type of spark plugs, it's best to stick with the manufacturer's recommendations. In this case, NGK spark plugs are the most suitable for your Kia Ceed.

However, if you frequently drive in harsh conditions or have high-performance modifications, it's best to change them more frequently, even as often as every 20,000 miles.
