do NOT use anti seize use motorcraft plugs and tq to spec. anti seize gives you an innacurate tq. plus these plugs have a way of working themselves out. use the motorcraft plugs they have aluminum threads for your aluminum head. if not tourqed properly you will have problems, too tight you break threads too loose and spark plug comes loose and combustion causes it to rip out threads on the 2v motor go by the book. its amazing everyone goin by "the book" and not "their" own personal preference is having no problems
I ran ngk tr6's in my mustang and many other vehicles for well over 8 years making 200rwhp to 700rwhp and used anti-sieze on every single plug with 0 issues...never had threads come out or a plug blow out...now those that used motocraft plugs with no antisieze is a different story as I made money heli-ing the threads and removing stuck plugs...
The reason you use anti-sieze on a non aluminum coated plug is due to difference in the metals heating a cooling cycles...with the motorcrafts no anti-sieze is needed as the metals are like and will expand and contract the same...with unlike metals you need the anti-sieze because the heating and cooling of 2 different metals can cause the threads to bind and then cause you to pull threads out with the plugs...
The book also says to only run BP gas..."the book" isn't always right...also a plug should never be torqued period that's what causes plugs to bind and porcelains to break...should be snug and no tighter...
