How often should I change the spark plugs in my Kia Soul?

I've noticed a decrease in performance and gas mileage in my Kia Soul. I suspect it may be due to old spark plugs. Is there a recommended mileage or time interval for changing them? Any tips on choosing the right spark plugs for my Kia Soul?

It is recommended to change your Kia Soul's spark plugs every 30,000 miles or every 3 years, whichever comes first. As for choosing the right spark plugs, make sure they are compatible with your Kia Soul's engine and performance needs.

I would suggest getting your Kia Soul's spark plugs checked and replaced if necessary. Old spark plugs can lead to engine misfires and decrease your gas mileage. Make sure to choose spark plugs that are specifically designed for your Kia Soul model.

I have a Kia Soul myself and I found that changing the spark plugs every 50,000 miles worked best for me. But it's always a good idea to get them checked by a professional mechanic to determine if they need to be replaced.
