Furtherer thoughts (edited)
Coils 1 and 3 (passenger side) are now changed out, and only coil 4 on the driver's side "needs" to be pre-emptively done, but the very-difficult-to-reach location makes it a dealer job.
Thoughts on the previously mentioned loose O2 sensor:
The passenger forward sensor was even looser than the other bank's. I gave the lead a bit of a ccw twist before screwing the sensor in, with the hope of counteracting some of the ccw tension, but I don't think it helped much. I didn't force it further so as to avoid possibly damaging the lead's connection to the chassis wiring. Being the coils are not the easiest things to get to, I sure didn't want to deal with a busted connection somewhere in the dark recesses of the car.
I currently entertain the hypothesis that the factory can install the sensors while the engine is still out, and the leads are free to turn. It's afterward, when spark plug or coil replacement comes up, the job in doing each forward piece is a lot easier with the sensor out of the way. Then, when being reinstalled, the issue of ccw torque comes up.
One other thing: the nature of the sensor threads is such that when tightening, the piece is loose... it's loose... it's loose... then it's tight. I found once it's home there's very little turning, if at all, that can be done, even yanking on the O2 wrench with about 80% of what I could do. I'll check on them at least with each summer/winter tire change.
