question again on the torque. In the TIS on page one, it called for the BMW tool 121172 for tightening down the spark plugs. I did some more digging and it seem that the torque spec on this tool is 23 Nm. I also read some indicating the torque should be 30 Nm. This is a good 30% difference in torque. Can someone confirm what the real torque should be for our engine? I read on the S85 pdf that the torque should be 23 Nm +/- 3 Nm.
