Anti sieze on spark plugs

[trex]

I thought I was being pretty smart by using anti seize on the spark plug threads but a NGK technician told me not to do that as they have an anti seize substance on them and using anti seize can cause detonation. I'm always nervous pulling plugs on my bike, would hate to strip them. Is  what I was told true of all plugs used on Harley's?

I use it all the time and as far as detonation... Never hear that folk tail especially since it is applied to the threads and no other part of the plug.  I would hate to rip the theads outta a head unessesarily.

Over applied it can run down into the electrode area and shorth the plug out so only sparingly coat from the first 2-3 thread on up, and very lightly. Tech is full of poop. Only coating is the plating. One of the down sides some of us are seeing is anti seize can pack up the threads making the plug tight to remove and some are using a drop of syn instead. Havn't tried that myself but have witnessed tight plugs on removal. Good thing is they always come out.

I thought it sounded like a lawyer covering his ass. I will continue to use it, thanks guys. And yes I use it sparingly, I don't slop it on.

i realize its to prevent galling just not sure if thats considered a conductor or an insulator? but if it ran down the plug and shorted i can see it being a problem

Use a spot of Hi Nickle antiseize and torque to the low side of the specs.

[turboprop]

Is that synthetic or dino based antiseize?  <smirk>

I was using too much on my '05 and was checking them often for the bad valve seals, caked up a bit and stripped the threads. Just use a drop of oil now.

Tre' read the article I posted up here and make up your own mind......

As in any steel threaded insert/fastener with dissimiliar metals,I.E. steel spark plug and with aluminum heads antiseize copper or silver used in a small application,   Oil will "bake" on threads , and always use a torqe wrench, something simple like this done halfa$$ed will ruin a afternoon

I have been using antiseize on sparkplugs for over 25 years. I have had more trouble not using it than using it. I am sticking with antiseize, but just a tiny dad will do ya.

I'll add another 10 years at least to that. Never a problem for me getting the plugs out. I put it on sparingly, then wipe my finger around the threads. It leaves a very small amount in the gap between threads.

What is the consensus among the guys that use it on plugs, silver, copper, nickle or graphite like the Champion stuff?

I use the Champion stuff. Much better for plugs than all the others.

[Sixspeed]

I use Permatex

I use Permatex

Me too. Haven't had any spark plug problems all the time I've been using it.

[WhipLash96]

I do not use anti seize and never have and never will. 

[Barrett]

I use a very small amount of Permatex, I put it on with a little model brush. I use a TQ wrench too.

I 'think' most anti-seize compounds are electrically conductive.  If you used something that was not conductive I wonder if it might weaken the spark?

[Golfman]

I noticed today the the "Fix your Hog" video CDs recommend a dab of anti-seize on the plug threads. They used an anti-seize stick, which I couldn't find.

[charlie]

I can't believe you blokes, TQ wrench on a spark plug i suppose you use one on your car to when you change the plugs,never used one or stripped a spark plug or sump plug leave it alone and give it to someone who can that has the touch,oil on the thread.

I was told years ago by a guy at the moco not to use the copper anti seize cause it messes with the ion sense. Just repeating what i was told. He was the head of the powertrain division not a janitor.

Wonder if is the same guy that thinks .008" of runout is ok?

Jeffd,

Now I thought they moved it out to .012 

.012 leaves fewer problems,,,, Doesn't it?
