When to change spark plugs? Car has no interval
Call or go to the dealer, give them the VIN of your car, have them run the service history and see if your spark plugs have been changed. If they have, you should changed every 30-60K miles depending on your car driving habits. the idrive will tell you, eventually, when the service is becoming due.
