I went down to Autozone with an old plug, looked at their NGK BKR6EQUP and the numbers were in the same place and matched exactly. The housing was the same shape as well, so I figured I would give them a shot seeing as they were $6.99 each (55.92 total for 8).
The old plugs came out very easily, which was surpring seeing as they had been in for 9 years and 122,000 miles and they were in much better shape than I anticipated. They didn't really look that bad. To be honest, even changing these out for the first time at 122,000 miles, I have not noticed any "restored power" from the new plugs.

My Indy BMW shop here in Naples quoted me $264 for plugs on my 3.0L 6.
I have always done my plugs myself and had to laugh as they told me they always used BMW OEM plugs with a $18/each cost plus labor. Those NGK's are the exact same as OEM.
As far as antiseize goes - I wouldn't recommend it. I do use antiseize on my Kawasake Jetski with Super Charger and 275 HP inline 4 cylinder 1.5L motor. We run in saltwater and a very corrosive atmosphere. The heads are aluminum and it is easy to strip a plug trying to get it out. Auto land is a much different environment.
Off to Autozone manana to get some $7 buckers.......
