Maintenance time…
plugs and coils. Took a friend and myself 3 hours start to finish. That included 30 mins of figuring out how to get the car on his lift.
That is a pretty impressive time considering how much disassembly/reassembly is required to get to the plugs on the Turbo!

honestlly didn’t have to remove much at all…. Rear wheels, plastic liners, plastic turbo inlet tubes, turbo shields. The rear driver side coil was the tricky one but just had to remove the turbo shield, after we clocked the coil right it came right out. Started at 11am today and was off lift and drove it to lunch for 2pm. After reading the threads on here we were expecting the whole afternoon.

Hope I'm not taking this too literally, but you were able to do the plugs and coils without pulling the intercoolers and racks (and by extension, spoiler, tail lights, bumper cover)? I assumed the intercoolers pretty much had to come off do do that job. I know trying to do the plugs on a 996 Turbo without pulling the intercooler racks is nearly impossible (though some have claimed to do it)
I'm happy to hear this upbeat field report! Looks super-clean in there - does the car have 30k miles, or doing plugs more based on years?
Thanks. Car is definitely clean. It has 14k miles but is a 2016 so I’m doing it based of years. $400 and 3hrs of my time is worth the peace of mind.

correct. We didn’t remove any of that, just what is pictured. The plastic wheel liner, the plastic intake tube on the turbo, and the turbo heat shields. I have a catless boostlogic exhaust. Maybe that’s what made it easier? Not really sure.

I’m starting this plug dance on my bone-stock Turbo today. I will report back. (Note though that I never try to ‘beat the clock’ and that I’m down a thumb temporarily, so don’t hold breaths.)

good luck, its just a matter of turning wrenches. I never rush working on cars, we just planed it all out . my friend definitely helped a lot. my arms/hands are shot from carpel tunnel and other issues, I can only turn wrenches for so long before I have to take a break.

I spend about 1000 hours per year wrenching on other people's 928s.
Doing it on my own cars isn't the cathartic experience it was almost 25+ years ago when I got my first Porsche.
On a 928 it takes 30 minutes to change the plugs. A couple of hours on my wife's 991. And about 3 hours on her (former) 981.
I spent over an hour under the Turbo taking pieces off in my head. What a jigsaw puzzle.
The shop manual procedure is a joke.
The heat shields over the coils have to go (duh), but the center bolts won't come out due to the turbo shields. Actually, they'll come out, but won't go back in. So, the hot-side heat shields have to go, but they can't be removed with the giant stock converters in place. Can't get to the upstream 02 sensors from underneath. And it's not clear if the converters will come off with the muffler in place. It looks like the muffler and cats need to be loosened and "dropped down" a bit to disconnect the 02 sensors and then the assembly removed. Once done it looks like the #1 coil (left-side rear assuming 911 cylinders get numbered opposite 928 cylinders) is still going to be "interesting" because of the turbo.
Tomorrow I'm going to pull the spoiler and rear cover.
