MasterScheduled maintenance calls for new plugs every 60K. You have to remove the plenum on this model though and will need that gasket. Use the highest quality plugs you can find since this repair will take you about three hours. If this is out of your comfort zone you can take it to a qualified independent shop for about $400.00. Good luck.
