Getting ready to replace plugs with iridiums, and want to use anti-seize on the threads. How much do you use - e.g. - are the threads completely covered, or would running a small amount down one side of the plug suffice, so that as it is tightened, it would spread around the threads? Thank you in advance.

I use a Small amount.

This topic is as controversial as What kind of oil do you use.
Some claim dry threads for spark plugs is best.

Not a good idea to use anti-seize on spark plug threads. The plug threads are used as a electrical conductor to ground. You want a good ground connection, so no anti-seize.

See....

I use the copper type of anti seize because it conducts electricity.

Ditto
I worked in an engine shop and saw too many stripped plug threads from stuck plugs to ever consider not using it.... Copper or aluminum based anti-sieze will conduct electricity just as well if not better than a dry joint. Dont use too much just a dab will do yah

+1 on the copper anti-sieze. Again, people are going to have their own opinions but IMO, even if you use a non-conductive anti-sieze, the plug threads will still make plenty of contact to allow current to pass though.

+1 on the anti-seize; just smear a small amount INTO the threads with your finger and wipe off any excess on the unthreaded portion of the firing end with a clean rag. I've been doing it on all my plugs for years; they come out much easier.------James.

Just a smear. Neglect to use it and one day, the thread will wind out with the plug....

To those who think that a lubricated plug won't conduct electricity, no offense meant and all that, but I've never heard so much pants in all my life! Or maybe American electricity isn't as good as English, ho ho.

denny

pants? Is that like B#ll $h!#

Yes, a very good approximation.
The basic expression 'pants' may be enhanced thus;

What a load of frilly big ladies old pants, etc etc.....

you can sort of free style with it.

Like; Gordon Brown thinks he has just saved the world, what utter pants.

Like; what do you think of gold Wings?
Pants.

These are English pants, be aware. American pants=trousers, unless I am mistaken.
English pants can equate to panties AND jockies, paradoxically.
What a minefield!
