I extracted a RER8ZWYCB4 plug from cylinder #1 of my 2011 Chrysler T&C 3.6L engine, the second plug in there for two years and the vehicle now at 135K miles. I had to use my 18 inch wrench with two hands to remove the plug. The top 5/8″ of the thread looks OK, the bottom (near the electrode) has something(?) in the thread. Is there any way to post a picture of the threads? The new plug will not even start. In comparison, plug #3 goes in and out easily over the entire thread length until it seats. 🙁
