05 Spark Plug Change

OK so my car just hit the 70k mark and I'm pretty sure it's about time to change these spark plugs. Now I've heard plenty of horror stories of these plugs breaking off while being removed... and I'm terrified of it haha. For those of you that have changed your own plugs how did you get them out? I read that you can spray some lubricant in there? If you did what kind did you use? Also what new plugs did you end up using after you got the old ones out?

Let the plugs soak in pb blaster for about 20 min before attempting to pull them out. Then then loosen them a quarter turn then tighten back in place and then loosen it again but a little further. Keep working the plug back and forth, tightening and loosening it to extract it with ease. Do this until they come out. I used this technique and only broke the last one because I got anxious. DO NOT FORCE IT OUT!

+1
Just be patient. Be careful about spraying too much stuff, it's all going into your cylinder after you loosen the plug. I got all 8 out without breaking any. Loosen a little, tighten back, loosen a little, etc. There is a TSB from Ford about the process to follow you can get online.
they don't sell the 2 piece plugs anymore. So any quality plug will be fine.

Nope. Just get the lisle tool, I think it's this one. http://m.summitracing.com/parts/lil-65600

You can get one just incase if you want.
I think that's it, I never bought it. Someone else will let you know for sure.
There's videos on YouTube in how to use it.

I just did my 08 GT with 70K miles. They all came out but it took some patience and several applications of Seafoam. The trick was to run about 2-3 cans of Seafoam through the fuel system (I also added to the brake booster and let it soak overnight). The carbon was built up real heavy but using the Seafoam and following the TSB, I never reached anywhere near 30 lbs. of torque and had zero issues getting the plugs out. I had to work them back and forth and even let two sit overnight soaking (just playing it safe). I can walk you through exactly what the process was if you need more info. YOU NEED TO GET THE CARBON SOFTENED AND OFF THE PLUGS OR THEY WILL BREAK IN HALF. THIS IS THE KEY AND NEVER EXCEEDING 33 FT/LBS. OF TORQUE. JUST WORK THE PLUGS BACK AND FORTH AND BE SURE TO USE PLENTY OF SEAFOAM BEFORE YOU CHANGE THE PLUGS. YOU CAN SAFELY CYCLE THE MOTOR TO BLOW OUT ANY SEAFOAM THAT REMAINS BEFORE REINSTALLING THE COIL PACKS AND NEW PLUGS

Just curious if you guys are using torque wrenches to ensure that you dont exceed 30 ft/lbs of torque.

When you get all of the plugs out I would recommend blowing the cylinders out to rid as much penetrating oil as possible. With all of the plugs out, get into the car and hold the gas pedal to the floor (that shuts the fuel system off) then just hit your key to the crank position once or twice quickly. Just make sure that your floor mat is far enough back that you can push the pedal to the floor.

This is why I joined this forum! After reading the horror stories, and not wanting to mess up my Baby, it's good to get the little helpful hints. Thanks!
