    What's your take on this? Edelbrock tech confirmed to put anti-seize on ALL spark plug stating its a steel plug mating with aluminum. NGK says their metal is a special material that will not stick to anything and no anti seize is recommended because of potential over-torquing. Lots of YouTube videos confirming that NGK plugs do not need it.

    Everyone else I speak to says to apply anti-seize. What do you do?

    I remember years ago finding Champion plugs in the old VW engines, (aluminum heads) and they would be seized up. Had a hard time getting them out. We used Bosch or NGK back then with no anti seize. Champion uses a galvanize coating that will corrode even on iron heads.

      I always put a small dab on my stuff with aluminum heads.
      I don’t overdo it and I don’t pull on the wrench like a gorilla either.
      I don’t see any harm in doing it that way.

        I always use a dab of anti seize no matter what. Can't hurt.

            NGK don't require any anti seize compound. You don't need to have any fear of them sticking. They are used in every sport motorcycle and snowmobile made and they never stick, I have pulled hundreds with no issue. You are more likely to over tighten and strip the head before they will stick. Go by the manufacturer recommendation.

                    Sure do learn a lot on this site. Wasn't aware NGK didnt recommend it with their plugs. I will probably still use a bit of anti seize, but I never torque plugs as anyway, just snug.

                      Lucky for me that the only plugs available for my Edelbrock heads are Champion. :rolleyes:

                          Only an ape would over torque a spark plug. Anti seize - I put that shit on everything.

                            I have seen guys pull threads out of snowmobile heads. It doesn't take as much as you think. And I'd assume NKG warning of putting anti seize on plugs is because if you lube a thread and then torque it with a torque wrench the result will not be the same as torqued dry.

                              Use ngk plugs in 2.4 dodge where plugs are deep recessed into head through valve cover. Didn't have tough time removing them but did see fair amount of corrosion on the threads dissimilar metal aluminum and steel. I have read where they state don't use antisieze on threads. Done it both ways who knows.

                                  ^^^ What he said lol. I guess the better question would be why not use it? It's great that they don't need it but can't think of one reason to not go the extra step for insurance.

                                    The only reason not to use it is if you put it on like a whore puts on perfume and get it on the electrode.

                                      Just do it, lol, it won't hurt.

                                      Metals tend not to play well with aluminum. I sorta of agree with NGK's stance, if you look at their plugs compared to other manufacturers they do "look" different, but who knows.

                                        Always do, there is the copper anti stick that's supposed to be used on steel/aluminum mating surfaces. Haven't used it yet but I plan to soon.
