Well...25 minutes to d-day. Just pulled the coils, 1/8 turned each plug (one felt loose or it's already broken), and put 3/4 teaspoon of Motorcraft carb cleaner...see pics. I used a syringe to get the carb cleaner down in the plug well without spilling it..............WILL THESE PLUGS COME OUT WITH OVER 110,000 MILES?? ONLY TIME WILL TELL....
MISSION ACCOMPLISHED!!!!!!!!!!!!!!!!!!! NO TOW NECESSARY TALK ABOUT SWEATING BULLETS. ALL PLUGS ARE OUT WITH NO BREAKS. PRAYER DOES WORK. SO THE WHOLE JOB COST WAS $70 TOTAL (HT1 PLUGS $46 SHIPPED ON EBAY AND THE MOTORCRAFT CARB CLEANER + ANTISEIZE WAS $24 AT THE DEALER). THANKS TO ALL WHO HAVE PAVED THE WAY.
HERE'S THE PROCEDURE I USED:
DEAD COLD ENGINE
3/4 TEASPOON MOTORCRAFT CARB CLEANER USING SYRINGE IN EACH PLUG WELL AFTER LOOSENING 1/8TH TURN
LET WICK DOWN FOR 30 MINUTES
TURN ANOTHER 1/8TH TURN; WAITED ANOTHER 30 MINUTES TO WICK DOWN
USED SAME SYRINGE TO DRAW EXCESS FLUID OUT OF PLUG WELL TO AVOID ANY MORE THAN NECESSARY GOING INTO THE CYLINDER
REMOVE PLUGS VERY METHODICALLY - IF ANY NOTICEABLE RESISTANCE, REVERSE AND TIGHTEN 1/4 TURN, THEN BEGIN LOSSENING AGAIN.

As they say where I come from wasvette, PRAISE THE GOOD LORD!! I'm happy for ya bro! I'll be doing my Whipple install next week so I'll be on egg shells til all 8 of these things are out in one piece hopefully.
God doesn't care if the plugs break. He has bigger fish to fry. What gas have you been burning and what was the condition of the plugs? What mpg were you getting? Could you have gone longer than 110,000 miles?

AMEN ACLASS - PIC OF PLUGS HERE SHOWS THAT 6 GOT SOAKED BUT 2 (UPPER RIGHT) DIDN'T EVEN GET WET AFTER OVER 1 HOUR TOTAL OF ALLOWING CARB CLEANER TO WICK DOWN!
Those don't look any different than some I've seen changed at 25,000 miles. Good news for the rest of us. The 2 real clean ones may have let the cleaner go straight into the cylinder uncontested and evaporated after 1 hour.

PLUGS LOOK GOOD TO ME...ONLY DIFFERENCE I CAN SEE IS THE ELECTRODE LOOKS A LITTLE LONGER ON THE NEW PLUGS. CAR RAN GREAT WITH OLD ONES. I RUN AMOCO/BP AND SHELL 93 OCTANE USUALLY AND GET ABOUT 24 ON THE HIGHWAY USUALLY. I THINK I COULD HAVE GONE LONGER BUT WANTED TO GET THIS OVER WITH...AND IT WAS ONLY $70.

I DOUBT IT EVAPORATED BUT I DON'T KNOW FOR SURE. WHY WOULD IT EVAPORATE ON 2 AND NOT ON THE OTHER 6?

..and put 3/4 teaspoon of Motorcraft carb cleaner...
On each plug or total?
Richmod - EACH plug well...so 3/4 ts X 8 - The way I did it you could probably go 1 TS per because I used the syringe to draw out the remaining carb liquid around the plug prior to removing the plug.

The carbon wicked it up and held it. On those 2 clean ones, nothing to stop it from going right on through the threads and down into the chamber.

I have 3600 on the clock, '08 GT convert. My mechanic will give it a go. Might I ask what gap you are using, be it the champion plug or other. Thanks Bob

Bob - I'm using the Autolite HT-1 OE equivalent (I think). No gap necessary and it runs likes a scalded ape. I think the gapping thing is more relevant when you get into the FI set ups.
If you go with the HT-1, look around...
Dealer $17 per plug! Advance $12 per plug Ebay $40 + 6.50 ship for 8 plugs!!
Also, make sure you print the TSB for plug removal linked previously in this thread and take it to your mechanic.

When I did mine for my 07 Stang / Whipple install, took < 20 lb-ft to remove them. I sprayed some Kroil in each spark-plug cavity before, but it wasn't required at all. Car had 16,000 miles on it.
