B3freak: original Bosch FGR5NQE04 Super Bosch R5W plugs. P.O. was advised at 4 year mark to have plugs changed, he declined. Again at 37.5k miles, declined. I have his original work orders for all the work done at the Porsche dealer. Trust me, they were not changed. I got my Knipex extractors yesterday, no joy. The plug hole is in a tough position to remove the plug. Need universal joint and extensions, so you end up side loading the plug trying to remove it, and it snapped the plug at the hex. I really need to get a straight shot at the plug so I can tap the extractor solidly in the threads. I tried to “bathtub” the plug per HETPE3B’s advise ,we’ll see. Had to plug the hole in the busted plug with a wooden dowel to keep the penetrant in the plug access area. Wife said to give it a rest for awhile. Agreed, don’t need the grief. So yesterday, I changed the rear drop links, another p.i.a. project. Pinch bolt solidly stuck in the aluminum hub. I am a glutton for punishment….map gas is your friend, heated the hub near the pinch bolt, impact wrench on the 17mm hex heads, finally spun the pinch bolt out after a few heat-impact cycles. Another 3-4 hour job. Will attack this project again tomorrow. Keep you all posted, and once again appreciate everyone’s advice.

That's cool. I don't doubt the records from the dealership. Just curious if the PO attempted to replace them himself because he declined the dealership's quote. If the car was still under warranty, then he would have said "Yes" to the warranty service, but since he declined, apparently it was a super high charge. Like most that own these cars, I've personally declined stuff that was ridiculously overpriced by Porsche dealerships. For example, Porsche of Atlanta noticed my tag light was out. They wanted $170 to virtually change a light bulb! ha! Crazy!
Anyway, good luck trying to extract the broken plugs. If the procedure doesn't work, I'm afraid the heads will have to come off to remove the threaded section.
P.O. was not a car guy, paid dealer or Indy to do any work. Plugs are not warranty item, suggested maintenance per Porsche maintenance booklet. He didn’t have an issue paying for maintenance or general repairs, so cost to change plugs from an Indy or dealer wouldn’t have been an issue for him.
This is the type extractor I was referring too. I bought a set at my FLAPS many years ago. They are effective. Sometimes you may need to find a way to tap them on tight.
Take a look and see it they will fit in the plug well. Once you get them seated, they dig in harder with more torque

I've used these too and they work well. Never tried on a plug, but don't see why they wouldn't work.
i don't think those extractors shown in the link are deep well sockets and may not fit on a spark plug. unless, of course, the end of the plug has, conveniently, been snapped off or something....

Aaaahhh... I forgot about Porsche "limited" warranties. All of my Porsches have been used outside of any remaining warranty. Makes me feel better about my Volvos. We've owned many under warranty and they cover everything including wear and tear parts... yep, brakes, rotors, batteries... and yes, spark plugs. Just bought a 2015 XC60 T6 R Polestar. Crazy to think it's got 80 more HP than my Cayman. But... still nothing like driving the Cayman.

Oh Lord, foiled again. Stuck a wooden dowel in the threaded portion of the stuck plug to make a ‘dam’ to soak the threads with penetrant. Now can’t get the wooden dowel out! Must have expanded in the plug. Now I’ve got to try to pick at the dowel to remove it. This is not going well at all….
Good news, got the wooden dowel out of the threaded section of the plug tonight. Used a pick to break up wood and vacuumed it out of the insert. Attached pic is what I need to remove from the head. This was one of the plugs I took out, cut it up to see what size extractor I would need. Heat and cold tomorrow to see if the remains of the plug will thread out of the head. Wish me luck!
Well, if you can get a dowel stuck in there, I think your odds of getting the extractor in there are pretty high, but I have been known to be a "half full" kind of guy. Best of luck.
Great work, and excellent patience! Too often we go off and get impatient and cause more problems... glad to see you're doing it "right" and carefully! Awesome work, and hoping for your final solution soon!
