Yes anti-seize is a lubricant which means if a threaded fastened is "eased" into mating threads theoretically they're just as easily "eased out"----if this is true then a higher torque setting would seem to be called for. Relating to torqued fasteners its a "five on, one off......" rule where its put forth only one fifth of the torque is required to loosen a fastener. Naturally this precludes many many specialized fasteners but for spark plugs it might be very appropriate.

I'll use a nickel-based anti seize and torque Motorcraft plugs to 21 ft/lbs which seems to be acceptable. I'll also never go over 50K miles on a set of plugs either!

Along with the thread you cite there should be enough good and real hands-on experience with this process.

My own experience discovered the COP connectors are subject to losing their locking tabs which can be its own source of aggravation.

Oh well..................
