Best way to remove broken spark plug

[Lessor1007]

Hey guys, just had a spark plug break off AFTER the hex, which meant all i had to work with was porcelein and the inside of the plug, this is what we did and it worked perfectly and nothing fell into the cylinder.
1. Chip away porcelein with phillips head and then use needle nose pliers to pull remaining porcelein portion of the plug out.
2. Once the porcelein is out use and extractor set, 12.99 at Sears, it looks like a cone shaped extractor tool. Wedge it into the remaining portion of the plug, just underneath threads. Pound tool in till its stuck, use 3/8 socked and pry on this till it spins, it worked in my case and saved me alot of $$, make sure to soak the plug overnight in PB Liquid Wrench.
3. Once extracted crank engine a couple times without starting and blow out ANY crap that might of droppped.
4. Install new plug and your ready to go, hope this helped!

Cool. Great info.
My brother snapped a plug off in #8 cylinder in his SS camaro just a couple months ago. Couldn't get any kind of tool in there so we ended up removing the head. PITA just to remove a broken spark plug.

Do NOT buy that one from Sears! It's called "Screw Out" and it's a *************! Buy the Black and Decker one - it's actually made of a harder metal.

I had a "screw out" extractor BREAK OFFF inside a fused screw on my wife's Honda rotor....needless to say I'm having to replace the entire pass side hub for a whopping $200 more now.

There's no way (that I'm aware of) to extract and extractor. You generally want to drill out the screw with a bit that is harder metal than the screw. Well, what happens when your extractor breaks off inside that hole? Not a "hole" lot LOL....I bought new bits and everything, still couldn't drill that extractor out.

I've used some cheaper sets before and they just end up snapping only after a few uses, or even the first or second use sometimes. I've had my Snap-On extractor set for a couple years and used it many times w/o any probs. Yea, it costs more from companies like Snap-On, MAC, Matco, etc, but better than constantly buying new bits to replace the cheap broken ones.
