3.0 Died after 115,000 miles

Well I did a quick search and it is happening a lot with Bosch plugs. I should have gone with the plugs with 4 arms cause they trap the broken ceramic. It sounds like Bosch might do something for me. Keeping my fingers crossed. This is not my plug but check it out.

I've heard of the platinum electrode coming out of the insulator and doing cylinder damage with Bosch plugs.

I had the plug ceramic center blow out on a 5 ton truck I had bought several years ago (not Bosch). Luckily I was on the way to the dealer at the time and so I just ran it with the piston blowing compression out the spark plug hole. It was easy to fix as the hex part of the plug was still threaded in. I also had a non Bosch ceramic tip break on a chain saw but when you removed the plug and turned the plug tip side up to inspect the ceramic slide back down the electrode so you could not tell it was broken. Drove me nuts for a while because I could not figure out why the saw would not start. Once I turned the plug tip side down I saw immediately what was wrong.
