Based on what my trusted mechanic friend ... he showed me the results - numbers of the coil in position 4 were far far higher than the other positions. He switched the coils between #4 and #1 and ran the tests to double-check; sure enough, now #1's results were out significantly erratic.

Do you think this is a good idea for preventative/upcoming 100k maintenance? Also do these coils fit a 550? I'm asking because Amazon says they do not fit (I know fitment guides aren't always correct) and I want to make sure they do before I buy.
Is this the plug you guys were referring to? NGK (6441) ZFR6FIX-11 Iridium IX Spark Plug, Pack of 1 : Amazon.com : Automotive
Thanks in advance.

Based on what my trusted mechanic friend (who also works @ a BMW dealership) did, it looks you do need to hook up the car and run the tests to determine which one is having an issue. It took about 30 minutes and he showed me the results - numbers of the coil in position 4 were far far higher than the other positions. He switched the coils between #4 and #1 and ran the tests to double-check; sure enough, now #1's results were out significantly erratic.
I am sure more experienced members can chime in on alternate methods.
Plowery and Trinity - thanks for the feedback!
