Installed a set of Champion Platinum plugs in my C280 about 85,000 miles ago. Never checked the gap and have not done anything related to the plugs since. Car runs perfectly and I wonder if it will ever wear out? But keep in mind, MB are almost maintenace free and require very little under the hood adjusting. Really, they are very much like Fords and Chevys.
