Omg! Emergency! Broke Spark Plug In Engine!
wow.. haha.. never seen that happen before. i may be wrong.. but u can probably tap it out just like a regular screw that got broken off.. you need a tap and die set.. i seen one at big lots for like 10 dollars.. give it a shot.. its gonna be a bitch to get down in there though..
you need to clearify this more...like the back part of the plug broke off and the head of it is still stuck in the spark plug socket? Or did you somehow break the actual sparkplug into the rotor housing (which i think is impossible... but hey it can happen).

So the part that the cosket goes over is gone, right? If so, how did you do that? I've had some majorly stuck sprark plugs and that never happened before.
As for getting it out, I guess you would have to tap it out like a broken bolt.

I wouldnt try to get the plug out with a tap and die set, those make new threads. An easy out would be a much better choice.
I think that an easy out is the only real way to go if its broken off.

that JUST happened to a friend of mine. his broke off at the head, left just threads and porcelain in the engine.
first they chipped out the porcelain, carefully. then you need a reverse (coarse thread), most likely an easy out, and work it out..

I dont see why its not weldable. But it would take a damn good welder.
EDIT: and the chances of welding the plug to the housing just from the heat would be pretty great.
I would use some poxy and poxy on a bolt after chipping out the porcelain. Once thats done wait a couple days and then try and twist that sucker out.
Before you do that, you might want to use some penetrating lube, as in a lot, just cause I bet it broke off becuase it was siezed in there in the first place.
You need to be carefully becuase if you **** this one up, you're going to need a new housing, either that or you won't have a trailing spark anymore...

It happens. I did it to an engine that has been sitting for a long time. It was not an NGK plug. Why do the NGK plugs glide right in while any other brand has trouble getting in there smoothly??? Mine broke in the leading hole. Needs to be rebuilt anyhow.
