Just go nice and slow, keep working them back and forth as suggested by a few others.

geo06 Like Boss said, it doesn't happen to us "old school". I lost count of how many times i have taken the plugs out cleaned them/replaced them with new ones, and never broke one. Is called maintenance.

Tpony Thanks for sharing....haven't done this yet. But I only have about 27K miles...

Durr4456 Never said it wasn't. But I couldn't run the engine, so I didn't have a huge choice.

And the tsb was more work lol. It worked out fine for me.

That's probably why 5 of them broke.

If you warm up the engine beforehand they are easier to break loose, then you can start soaking them to start dissolving some of that carbon buildup.

You only hear about the horror stories. You never hear about all the thousands of times they have been changed without any issues. I mean I know it is a known issue that can rear it's head at any moment, but if you don;t hear about all the successful plug changes your view is going to get a little skewed. Just prepared for the worse and go at it. Being scared aint going to help a thing.

I broke 5 of mine. Only 1 was actually difficult to get out as the barrel broke. But the lisle tool helps everything. It's really not that bad.

07 Boss Maybe I'm old and cars don't need it these days but I pull my plugs at least once a year if not 2 or 3 times. I check the condition, clean them up and check the gap. The one byproduct of doing this preventive maintenance will make it so spark plug breakage is never an issue.

Haha, yeah, the noise is definitely unnerving. I had one that I swear was making crunching noises when I first started turning it out but it all came out intact.

The driver's side rearmost one screeched and scraped and made all kinds of godawful noises but also came out intact.

PB Blaster and/or some kind of carb cleaner or seafoam is your friend on this job. I mostly used PB Blaster and it immediately dissolves any carbon buildup that it touches.

Bagel_Dog I personally didn't have any issues. My engine has 165,xxx miles and these looked like original plugs possible they were the second set.

I sprayed in some PB blast and let it sit for a few minutes then used an air ratchet. Not a single one broke.

ChewyR I broke 2 even after soaking with brake fluid. 1st one porcelain came out intact, just had to get the shell out, used an easy out. 2nd one PITA, watched video on how the lisle tool worked, (didn't have one), tapped the electrode/porcelain down, ran a 3/8 tap into the top of the shell, long piece of all-thread into the shell and a deep well socket created my own puller. I got it out but it took a few hours to figure out. Saved myself the cost of the tool and the wait.

Towelie I guess I got incredibly lucky at 83K, took out the factory spark plugs without any of the "tricks" so to speak. Just got the correct socket and went slow and didn't break a single one.

AR Stang The noise is horrifying the first time you take these plugs out. That was the part I hated the most.

05Nlstang i know that i am really bring this one back from the dead but i thought that i would share how the change went. first of thanks for all the advise i ended up having to put my torque wrench on the plugs just to get enough leverage to break them free. i wasnt to worried about busting them off because i had the lisle tool. i ended up buying a 9/16 spark plug socket and then drilling out the rubber insert so that the oem plugs would fit and hold in the socket. overall i only busted one plug. i did learn that if it is not making a bunch of noise when you are taking it out start to get worried lol. thanks again.

ghunt I changed mine at 80K last winter. Cracked all the plugs a half turn, soaked them in PB blaster (I was in no hurry so I let them sit for a day or so at a time) and slowly worked them out a half turn to a turn at a time.

Apparently the two rear plugs are generally the worst, the drivers side one came out tough but did all come out in one piece. On the passenger side rear plug the hex and accompanying threaded part came out but the main body of the plug stayed put, I guess the tip was THAT seized in there. So I had no choice but to break that one off (it wouldn't budge) and get the Lisle tool which worked like a charm. All the others I turned out with a 3/8" ratchet so as to not apply too much torque but they came out fine.

I replaced them with E3 plugs because they were the best deal I could find on a one piece plug. They've been in the car for 5K now and no issues, I might pull them this winter and see how they look.

07 Boss I don't have any horror stories to share. It really doesn't matter if it's a two piece or not. Maybe I'm old school but I am constantly pulling my plugs. Maybe not constantly, but at least twice a year and that's maybe 3K miles. If you let them go 80K-100K miles you will have issues I feel with any plug. Checking plugs is a quick cheap way to look for signs of many engine issues. And it doesn't hurt to clean them. This should be routine maintenance for any car. If you get in the habit of doing this you won't ever have any issues with the plugs breaking.

AR Stang I have brisk in mine for the stock heat range since I am not modified. I don't see why someone would put 2 piece plugs back in and worry about them splitting again down the road.

I think you could go with the other brands and probably be fine, but my thought process is once something needs replacing I am going to use either an OEM replacement or the best aftermarket product I can get if OEM is not acceptable, which in this case it was not.
