    My 2004 has 102,600 miles on the original spark plugs. The car runs great and fuel economy is as good as it ever has been. I am wondering if I should change the plugs or just keep using them as long as the car continues running this well. Anyone out there with more miles on the original plugs?

    The recommended service interval is 120K miles. I suggest that you replace the spark plugs at that point if you don't choose to do so earlier.
