What parts are necessary to perform 100,000 mile tune up?

Please check the RepairPal estimator to find the parts needed and cost for the 100K service on your 2004 Pontiac Sunfire. The "major" service should have been done at 90K. If you have not yet changed your spark plugs perhaps you should choose that service and add the necessary "addons". Here is the link - https://repairpal.com/estimator/pontiac/sunfire
