FYI...Doing more research about using anti-seize, I came across this post from Dave (WVZR-1) in 2014 and will repost here. The following is taken from the NGK site and refers to using or not using anti-seize on their IX plugs....

"1. Anti-seize
NGK spark plugs feature what is known as trivalent plating. This silver-or-chrome colored finish on the threads is designed to provide corrosion resistance against moisture and chemicals. The coating also acts as a release agent during spark plug removal. NGK spark plugs are installed at the factory dry, without the use of anti-seize. NGK tech support has received a number of tech calls from installers who have over-tightened spark plugs because of the use of anti-seize. Anti-seize compound can act as a lubricant altering torque values up to 20 percent, increasing the risk of spark plug thread breakage."

I think I will not use the anti-seize after reading the above, and torque to spec. I rather check and re-torque if necessary in the future....
