Let me start by saying I came from a Gen 5 Camaro SS. I am pretty sure my 6'6 frame can fit on either side of that V8.
Changing the spark plugs on my E92 M3 was the biggest PITA. By the end, I couldn’t feel my finger tips from trying to pull the coil packs out even after doing the coat hanger method.
To do a spark plug change on a BMW E92 M3 you have to basically disassemble most of the engine bay. The driver side airbox has to be completely disassembled and most of the top area near the windshield. Some people even take the engine plenum apart, but it is not needed.
Eventually I finished the job, but the worst part is due to all the stuff you disassemble, if you have a misfire or throw a code you have to re-disassemble so much I imagine a hole would be put through a wall if it happened. Luckily for me, I threw no codes and no misfires.
It was a bonding experience with my car, but next time, a BMW tech is doing it.
Here are some shots from my spark plug change.
While I was performing the spark plug change, I also replaced some of the engine bay hardware with Titanium hardware.
Then finished with an oil change.
