Spark plug broke in half while removing
I was having some engine stuttering between 800-1400 rpm so I decided to check the spark plugs I just installed not even 6 months ago. The first one I removed was obviously defective. The white thing that protects the spark wire was loose and was moving freely up and down (I'll attach pics) so I decided to check all of my spark plugs. The second spark plug I attempted to removed completely cracked in half. Only the top came out and the treaded part is still threaded in the combustion chamber. Does anyone have any thoughts on the best way to remove this? Any input would be greatly appreciated!!!

I have no clue how you are going to get that broken plug out, but this definitely looks like a case of over torquing the plug when you installed it. Also, I have to wonder if these plugs are 'real" and not Chinese knockoffs.

Check out the thread on forum on how to tell if NGK are fake https://f30.bimmerpost.com/forums/sh....php?t=1587651 Videos: https://youtu.be/PjBjVjcLcgc https://youtu.be/Lr9J3eQk-kE Course that doesn't help you out at all with current problem - I agree that trying the EZout is best way to proceed at this point before you take it to dealer, but I'm guessing that's where you'll end up

I really hoping to avoid getting this towed to the mechanic. I'm sure it's going to cost a fortune. I'm going to give it one last shot with the easy out. Thanks for the input everyone. I'll update on the status

I feel your pain. I've broken many bolts but never broke a sparkplug. You need to get a good set of broken plug remover kit. Lisle kit sells for around $100 on Amazon. Spray some penetrating oil and be patient. Take your time. You don't want to break the remover too.
FYI, when you're removing sparkplugs or bolts and it starts to resist, tighten it back in lightly and try again. Repeat until it's removed. I use this method when I remove stubborn plugs or bolts. Never broke a sparkplug and I change my plugs every oil change. Good luck. |

After 5hrs of trying to remove the broken spark plug, over the course of 2 days and super sore hands, I had to get the car towed to an Indy shop. It's going to cost $420 to get the plug removed plus the cost of new plugs. I actually thought it was going to cost way more than that so while paying $420 does suck, I was happy it wasn't more! Hopefully I didn't do any other damage while trying to get the plug out and the car drives the same. Thank you everyone for your suggestions and comments!

Those look fake to me. NGK use a silver/ steel crush washer/gasket. I would buy a legit NGK plug, then take the ones you bought from the dealer, along with the legit one and show them at the dealer. I would demand a refund for the spark plugs and the cost of the repairs. I would also tell them that you are going to inform NGK about their selling counterfeit products under the NGK name. Not sure how far that will get you, but you can talk to the parts manager and threaten to put them on social media as well for not selling genuine parts.
That said, I have always been a fanatic about changing my spark plugs every year regardless of the service interval required. It’s really not necessary, but I do it mostly because I want to perform a health check; looking mainly for any signs of moisture or damage or heavy carbon buildup on the spark plugs. I always figured that since I’m removing the spark plugs, I might as well replace them. Spark plugs for these cars ain’t cheap, so I decided to invest in one of these: https://www.harborfreight.com/search...plug%20cleaner We had a couple around in the shop when I wrenched on cars for a living, they didn’t get much use, but they will with me now. At least this way I can clean my plugs and regap if necessary before reinstalling them when I perform my annual “health check.” Last edited by IraHayes; 07-14-2019 at 12:36 PM.. |

Dealer's have no incentive to sell counterfeit parts because parts come with a 2 yr warranty

To the OP, I would also print out a copy of the pdf a few posts back illustrating the differences between the real deal, and the knock-offs. Maybe don’t go in “hot” either and ask calmly to speak to the parts manager and explain the situation. I’m always inclined to go in half cocked because I think I have been taken in situations like this, but it could very well be that they have no clue either. If anything, it will alert them to the potential of having several of these knock-off spark plugs in stock that may cost them big time in warranty repairs down the road. If that is the case, they will probably be grateful that you brought it to their attention because you likely will have saved them a lot of money down the road in repair costs that they might have to eat.
