Record breaking 118,000 miles on original plugs?!? Just picked up a 500hp Mercedes AMG for a daily driver... Mercedes plugs last 100k miles figured I would check these being car has 118k.. weird thing is previous owner has all records of everything from Mercedes dealer why when it hit 100k did they not change the plugs?!?!

AMG really does know how to make a proper-sounding vehicle.

I replaced mine on my '03 Z71 at 113k. They probably woulda went a lot longer.

I sure I could have gone maybe 10k more max but performance was lagging out and my c6 was keeping up with it ö haha in all seriousness for a 4 door this car makes my c6 work to play... Kinda wishing I went e63 amg
