greasing new spark plugs. copper or normal?
« on: 09 July 2013, 07:32:52 pm »
Currently replacing my spark plugs and seem to remember that its a good idea to pop a bit of grease on them.
What type is better?
Thanks :)

A little bit of copper on the threads couldn't hurt I guess, but I wouldn't use anything else. The high temperatures from the engine will melt and destroy any other grease I expect and I wouldn't want to see the results...

Don't fancy putting copper on em. 

I smear a tiny amount of graphite grease on then.  The grease carrier will burn off leaving the graphite behind.

To be honest there should be any need to use anything.
