Spark Plug Issues
I am having issues with my spark plugs on my E63. I have broken 2 sets of plugs so far on my car and that is the only major issue that I have been having with the car. The first time I had the car towed to the dealership because I was sure that I blew it up, I was really worried that they would find out that the car was tuned and my warranty would be void. It ended up that a spark plug was broken so I had them change all of them and the car was fine.
I broke another spark plug but this time I limped the car home instead of dealing with the tow truck and I changed them myself. I installed non-mercedes plugs and they fouled out so now I am back on the Mercedes plug again but I don't know how long they will last. I keep tools and some spare plugs in my trunk now.
How many people are having these problems. I have talked to 3 people so far that have had the same problem and we are all on the same tune. If anyone else has had these problems can you tell me what tune you are using? I want to see if the tune has anything to do with it even though I highly doubt it.

What year is your car and what tune are you running? How far apart are your plugs failing (days, weeks, months)?
I have an M156 engine with eurocharge tune and I have not had a spark plug fail (stock plugs).

I had the same situation. Got the car towed as well. Now i have the tune and spark plugs from Renntech and no issues. If u look on the forum there are bunch of threads where people where having same problems with cars that were made between certain dates and they had bad spark plugs.

replace them with step 8 spark plugs NGK or step 9 loke mine and no problem, especially if your car is 2012 which doesn't have the addtional split cooling stuff.
or go with step 8 NGK and add aditional coolings to the car and split it.
the plugs foul due to heat.
