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?


+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 ?
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!

If no codes are being thrown use Chevron Techron fuel injector cleaner (concentrate). It solves rpm fluctuating upon cold start-up. Also, for most BMW problems start off by scanning your car with the Peake Research Tool. It contains the actual BMW codes. If you want to register a newly installed battery for free (just buy a $10 cable) and google/download BMWLogger
