2012 Mini Countryman Spark Plugs
Playin it a little cautious, daughters car, don’t want to take the car out of service, much less have to pull the head, during the virus from Hades attack. I had some plugs like that on my K1200, got gray hair reading the Bentley Any insight, experience, or information would be appreciated. Thanks Mike

Haven't seen any reports of FACTORY plugs having issues. Most of the plug breakage, cracked insulators (The white porcelain tops) and "thread pulling" are installer abuse/wrong torque settings, strong arm tactics, etc. See one too many, In a past life I have been involved in field engineering reports for Champion Spark Plugs 20+ years ago. 99% of these issues is from the installer not following any basic shop processes.
Q: Do you have a broken plug or a known thread damage issue or are you looking to change plugs and want a little reassurance that this application tends NOT to have any inherent issues? If yes, try the mini forums for details. Tip: Let the engine be cool to the touch, remove the coil on plug, use the right size wrench with a rubber insert, and lightly unscrew the plug. If tight, add a drop or two of WD-40 and let it sit for a while.

Thanks
Planning on changing plugs and coils due to check engine light. Looking for pitfalls and good guidance. Thanks so much for your help Mike

With coil on plug application always, check for install issues,water intrusion, bad grounds and add a spot of die-electric grease on install.

You don't want to be performing a potentially risky operation at an inconvenient time when it may not even be needed. What if the CEL is for some emissions thing? My data point on this: 2001 3.0i replaced the *original* plugs at 169.5k miles, shortly after getting the car No change before vs. after in terms of engine performance, MPG, problems, etc. Removed plugs looked pretty good. I bet I could still be running them. Am still on the original coils at 192k+ miles. Comment / opinion / conjecture - I think that when these high mileage plugs are spec'ed at 100k miles, it may actually be effectively indefinite (comments, StephenVA ?). Changing them at 100k miles may have more to do with preventing thread damage for when they eventually get removed. When I changed mine, they did not come out very easily, and I was extremely cautious. In addition to following StephenVA's procedure, I:
