I used to use anti-seize very sparingly on spark plugs knowing it affected torque ratings. However after attending a NGK spark plug coarse and learning about the nickle plating on some versions of plug's I stopped the practice.

I still use nickle anti-seize on my 05 Mustangs two-piece plug's as per Ford's tsb directions. On the plug's barrel/sleeve only, not the threads.

I personally do not use a torque wrench because I have been turning wrenches for almost 50 years now and have a gret deal of feel for how tight things are and if the threads are stretching or not. The only time I use a torque wrench is for heads or other places where the fasteners have to be tightened in stages.

I'm an A&P mechanic, arn't you glad we use Tq Wr on the planes you fly in, no matter how many yrs experience we have. A 'calibrated' elbow doesn't cut it.

May I ask what the TQ is? I am about ready to change the plugs out on my wife's '04 5.4 Expy.

Next time I work on an airplane I will use a torque wrench but until I see an error in my ways I will continue with what i know works. An automobile is not that life threatening.

After 50 years of working on industrial machinery I've got a pretty good feel.
