NGK is the OEM spark plug manufacturer for the S2000.
As Billman stated you should not put anything on the threads. NGK has a Trivalent plating that eliminates the need for anti-seize.
All of the plugs listed below by NGK are suitable for the S2000 according to the NGK website.
Thanks for the reply.
I'm totally aware that NGK plugs have a Trivalent plating which eliminates the need for anti-seize paste on INNITIAL installation (and in fact makes its use risky). What I was asking was what happens if the plugs are removed and then RE-INSTALLED - as with a valve inspection or simply to "read" the plugs?
The following post appears in various threads on this forum and is presumably taken from NGK's website although it doesn't seem to be there in its entirety any more. It would seem to indicate that anti-seize paste should in fact be used with subsequent re-installation. Very confusing:
Solution For spark plugs with special metal plating; do not use anti-seize on the initial installation. If a spark plug with special metal plating is removed and re-installed, only then should anti-seize be used prior to “ re-installation”.......................... The shell plating acts as a “lubricant” which breaks away from the main body of the spark plug during removal thus preventing the bonding of the aluminum from the cylinder head to the threads
Also I wonder when NGK started using the Trivalent plating on their plugs. Did the original plugs in my '09 even have the plating on them?

I did not look this time but I recall a few years ago when I checked my plugs before, that the NGK site (or the directions with the plugs) used "may" when referring to the use of anti-seize. (After initial installation) You may remove and reinstall once or twice without using anything. I have never used it when I did this. If there is any plating left behind it serves to relubricate on reinsertion. It may be a different story if you then used another brand of plugs without it.

They come with a flux capacitor fusion rig. I can tell you but then I would have to kill you!
But...I have no idea what torque you should use in that case. 20-22LB, maybe?
I've been using 24LB without anti seize.
For gods sake, DO NOT use anti-seize. Even. I have proven this on 4000+ cars. Yes it will harm a lot!! Using it is a waste. There is no danger of corrosion/seizing of the plugs by design of the S2000. In addition, anyone following the advice to use anti-seize and attempts to put 20 ft-lbs on the plug is likely going to destroy the threads.
