How often should I change my Toyota GR86's spark plugs?

I just bought a Toyota GR86 and I'm wondering how often I should change the spark plugs. I want to make sure my car stays in good condition.

It's recommended to replace your spark plugs every 30,000 miles for optimal performance. However, if you notice any issues with your engine or fuel efficiency, it's best to replace them sooner.

I change my spark plugs every 25,000 miles, just to be safe. It may be a bit early, but I like to stay on top of maintenance.

If you notice your car is struggling to start or has a rough idle, those are signs that your spark plugs may need to be replaced. It's always better to address any issues sooner rather than later to avoid more costly repairs.
