DO NOT LUBE NGK PLUGS!!
 

I just got off the phone with an NGK rep, found some interesting things.

1) Yes the Iridum IX are pre-gapped

2) You don't need a Torque wrench, just hand tighten them and use regular wrench to do a 1/3 tighten

3) DO NOT LUBE NGK PLUGS!! Very important he said, cause they already have an Anti-Seize coating on them, and lubing will make them prone to be over tightened!!

Good to know.

thanks for the info

Don't lube any plugs, per BMW TIS.
