spark plugs - any preferences?

Both Loren and Pelican got their information from Porsche literature (been discussed in the past as well), which is based on the dielectric properties of many types of anti seize. We have several thousand plugs running around without issues, all of which have metallic paste style anti seize on them; and in all the years we have been doing this, we have never had one gall or pull the threads out of a cylinder head. All you need to do is check your brand of anti seize for its conductivity properties, if it is conductive, as most are, you are golden.

Excellent ,practical advice(as usual)and validated by years of real-world useage.Thanks JFP
For the Chemistry geeks here is link to confirm. Do NOT use the marine grade antisieze !Chase the threads.

I have a lifetime supply (for me anyway 1 bottle ) of aluminum base that I have used for years

Which is best Aluminum, Copper, or Nickel ??

and does brand make a difference

Not tooting JFP's horn but I like information by doing....and empirical prof means a lot to me.

Aluminum is a good general purpose anti seize; copper is as well, but does not get along with some alloys such as stainless steel (can cause galvanic reactions) so you need to check before using it. Nickel has the highest temperature and corrosion resistance, but tends to cost slightly more.
