There are no wires.
First pull out your fuel injectors.
Then remove the fuel rails.
From there you will see 4 black "boots" on each side of the motor. These are your COPs. Pull those out to reveal your Spark plugs.
From there blow out each hole to remove any dirt or junk that may have gotten down the hole.
Then your good to remove them.

no wires. there are coils on top of the plugs. the coils will have little numbers on them, including 12029. the bolts holding down the coils are 7mm. make sure you properly torque the spark plugs.
fuel rails stay. ive done spark plugs on mod motors a few hundred times and have NEVER pulled a rail or injector.

Fuel injectors your right, don't know why I was thinking that but I always pull the fuel rails because its easier to work with them out of the way.

Maybe I just like being difficult. LOL
It still only takes me about 15-20mins to change them all.

Thats a little harsh man..
Anyways... you dont have to have the fuel rails removed... the only thing you need is a 10" extention and a deep socket...remove them easy enough.. you can always get to them just dont give up =P there is always a straight shot.. just fyi...
When putting them back in.. hand tighten... if any resistance.. turn counter clockwise till you hear it skip on the tip of the thread and try again... when you get it hand tightened, another 1/8th of a turn with the ratchet secures them without sceasing. Put the coil back over the plug.. you will NOT hear the old CLICK that you use to get with wires... when you have it on HAND TIGHTeN the coil on plug (CoP), then just like the plug, another 1/8th of a turn. DO NOT OVER TIGHTEN!!!! You tighten over 20lb of preasure.. you break the seat on the Intake Manifold.. its not fun replacing one so DONT DO IT PLEASE! Other than that your Done, Resecure the molex connector on your CoP and that cylender is done.
The passenger side of the engine is the hardest part... Air intake must be removed... and the last two you kind of have to fight the heater core return lines... Dont give up though.. break the plug loose and hand loosen..
One more thing.... Plugs arnt pregapped... I dont give a damn who tells you otherwise.. factory "oem" is .040-.042 Your GT requires .052 Please remember to do that.. it does wonders =P Good luck
In the meantime, get a Haynes manual and read up on it.

Maybe it is a little harsh, but I think the98stang is right. Good info btw.
