Ive done this several times on a cast iron head and re threaded several aluminum heads.
If all the porcelain came out from plug(sometimes the porcelain can be blown out by cranking engine over) try a easy out. I have a special extension for my easy out for recessed plugs. It can be done with a lot of patients and penetrating oil.
Advice for other answers;
If you drill it cover drill bit with grease to catch drill cuttings and drill slow and wipe drill bit off often and re-coat w/grease to keep cuttings from entering combustion chamber.
If not than remove head.

is it a ford ka ? this happen all the time with the original ford plugs, the correct repair is as stated above (remove the head and bore out from the under side) but i find its well worth trying a torques bit slightly larger than the hole down the centre of the plug,drive the torques down the hole with a hammer, don't be afraid to give it a good tap, the shock will help to free the thread, once its down about an inch attach a socket bar and apply pressure a bit at a time. I have been very successful using this method and there is nothing to loose as the head was going to be removed any way

Lots of answers, lot of work. Since the spark plug already has a hole through the center for electrode, insert an easy out and screw it out. That is if you can get to it. If you can't get to it, head removal is the only solution.
When you get it out and put in the new plugs, always use sparkplug antiseize liquid on the threads. Read the directions carefully, if you put on too much it will short out the electrode.

could you drill a small hole in it then tap it (put a screw thread in it) the tighten a bolt into then plug and see if when you unscrew the bolt the plug comes with it..
OR
find a drill bit thats the size of the hole must be snug (put it in one of the other spark plug holes to make sure it just touches the thread all the way round).. then drill it outand retap the thread. make sure that after you turn the engine over with the spark plug out to clear the debris.
if your not 100% get a garage to do it!!!!

You could take an easy out (extractor) and remove the broken piece piece that is still in the yl. head. you also stand a chance of some piece of spark plug that has fallen into the cyl. chamber, which will cause more damage then what you already have. Best thing is to remove the cul. head and fix it right.

it relies upon on if the ratchet is popping and the plug isn't. if that's so then the plug is stripped or are utilising the incorrect length socket, (I recommend a 6 element socket). if the socket is in simple terms fairly tight then determine you employ a six element socket and get a much bigger ratchet or a cheater bar. I you have a twin overhead cam engine and the plugs are between the cams (down interior the holes on the ideal of the engine) the the holes would desire to be partly crammed with oil and dirt inflicting the socket to not attain the plug appropriate then you definately would desire to bathe the holes. compressed air could artwork stable use risk-free practices glasses bear in mind plugs in simple terms have 2 sizes 5/8 and 13/sixteen

Drill a 6mm hole down the centre of the broken plug and use a easy out extractor to remove the broken plug ,re member to turn the extractor anti clock wise.
Make sure you clean out the cylinder before fitting the new plug

Most people will say remove the head, but as long as it isn't rusted in place you could also try using a very small drill piece and drilling two holes just big enough to be able to grasp with a pair of small mole-grips. Obviously drill them either side, then you may well be able to get a grip on it with the grips and unscrew it that way. Your chances of doing any damage to the engine are negligible but I'd drill slightly in just to be safe.

The safest way would be to remove the head, bore out the insides of the plugs and use an extractor kit. Any other way would run the risk of dropping pieces onto the piston heas and casing damage.

A garage would pull the head to remove the leftovers. Anything else would much more than likely ruin the engine.
