Per manufacturer's web page, I found NGK ILZFR6D11 plugs are set for 0.044" and Bosch FR7NP332 are set for 0.040".

Also, both NGK and Bosch are HEX(6 sided) plugs. Why do you need a 12 point 5/8 socket?

Thanks

+1 Bosch FR7NP332 are set for 0.040

+1, see pics below

+1, except I didn't use a torque wrench. Also OEM for the 325i is Bosch FR7NP332 and the gap is 0.040.

Don't rely on that. My plugs were supposedly pre-gapped because they are oem, but I checked the gap and they were all over the place. This might be a reason why some members are having problems when they start 'er up.

I am questioning the use of anti seize on the plug threads,
I have used it before, and I understand the possible chance of a plug seizing in the head.. but?

one, was there antiseize on the plugs you pulled out from the factory ? yes or no ?
thanks
Yes, when I removed the oem plugs they had anti-seize on them. It didn't smell like oil and it was little slippery and clear.

Just did this today. As Jesse Wilson stated, use a screwdriver to flip up the coil and then place the screwdriver in the hole of the coil to use as leverage (see pics below).

Also, I wasn't comfortable removing plugs 5 and 6 with the strut brace there, so I moved it out of the way by removing the nut using a 7/16 socket. (see the first pic). Just unloosen the nut and push it up and over the red battery connection.

Again, OP, thank you!
