Don't know if anyones seen this, but if your changing plugs in a 3 valve engine you need to do it this way to avoid breaking the plugs off.
SERVICE PROCEDURE
To remove spark plugs without damage, it is necessary to adhere exactly to this procedure before removal is attempted.
CAUTION: DO NOT REMOVE PLUGS WHEN THE ENGINE IS WARM OR HOT. THE ENGINE MUST BE AT ROOM TEMPERATURE WHEN PERFORMING SPARK PLUG SERVICE. REMOVING THE SPARK PLUGS FROM A WARM/HOT ENGINE INCREASES THE CHANCE THE THREADS COULD BE DAMAGED.
Spark Plug Removal Procedure
Remove the coil-on-plug assemblies and thoroughly blow out the spark plug wells and surrounding valve cover area with compressed air.
Back out the spark plugs no more than 1/8 to 1/4 of a turn. Using Motorcraft® Carburetor Tune-Up Cleaner, fill the spark plug well just above where the jamb nut hex sits (1/2 - 3/4 teaspoon). A minimum period of 15 minutes of soak time is required. The cleaner will wick down to the ground electrode shield and soften the carbon deposits in this time. DO NOT WORK the spark plug back and forth at this point.
NOTE: COMPLETELY REVIEW THE PRODUCT LABEL FOR THE MOTORCRAFT CARBURETOR TUNE-UP CLEANER PRODUCT - USE AT ROOM TEMPERATURE AND SHAKE WELL.
CAUTION: EXCESSIVE MOTORCRAFT® CARBURETOR TUNE-UP CLEANER, OR REPEATING THE PROCESS SEVERAL TIMES WITH TOO MUCH CLEANER FLUID, COULD INTRODUCE ENOUGH LIQUID VOLUME TO HYDRO-LOCK THE ENGINE.
CAUTION: DO NOT USE AIR OR POWER TOOLS FOR SPARK PLUG REMOVAL. SPARK PLUGS MUST ONLY BE REMOVED WITH HAND TOOLS.
Tighten, and then loosen the spark plug, working the plug back and forth. Some screeching and high effort may be noticed. The expected removal torque is about 33 lb-ft (45 N-m). Repeat the back and forth turning as needed until turning effort is reduced, and remove the spark plugs.
NOTE: NEW PLUGS SHOULD BE INSTALLED USING A FILM COATING OF MOTORCRAFT HIGH TEMPERATURE NICKEL ANTI-SEIZE LUBRICANT ON THE GROUND ELECTRODE SHIELD. DO NOT COAT THE ELECTRODE STRAP.
