I just want to say THANK YOU to @polobai as this was a much needed topic (for the 991.2 specifically). While you do a nice job with the explanation and photos, I'm not sure I feel very encouraged to tackle this one as a DIY. Maybe that'll change. Dealer wants 900 and indy wants 700 to do this all-inclusive (parts & labor). Seems like getting that one tricky plug is what scares me the most.
So far, not that bad (only did drivers side) but would rate it more on the technical side that the laborous side. In all, would probably rate it a 6.5 out of 10 but you should be confident with turning some wrenches before diving in and have a good assortment of tools. The most careful part for this spark plug change (and any) would be to ensure the new plugs are installed properly and not cross threaded. On the 991.2 it makes it a bit harder as the spark plug is not at zero degrees in the hole-but angled about 20 degrees downward. Honestly, I think the $900 charge at the dealer is a fair charge considering the amount of work and time it could take. I would say it would take a solid 3-4 hours for a tech on a two post lift with the correct Porsche specialty tools. Comparatively speaking, this is easier to do than a header change on the 991.2. If you can tackle that, you can tackle this.
Yes, I have. Alot more stuff has to be removed for that to be done-I tackled it when I did the Tial inlets about 8 months back. In retrospec, I should have done the plugs then as the intercoolers, cages and hoses were out and everything was easily accessible. It all works out in the end-now you guys can see how to do it without having to pull all that stuff off.
Back when replacing the air filter and inlets. Perfect opportunity to get the spark plugs done.

I am sure you can do it. The biggest fear is just diving in to take it apart. These cars come apart quickly and go back together pretty easy (minus the rear suspension).

Good to hear from someone who has done it, looking at your pic of changing the engine air filter. I just had to replace a fuel line on my daughter’s VW Golf Mk7 that got chewed through by a rodent, and it looked like it could be assembled by a five-year old, but getting it apart was a nightmare.
Thanks, I have heard conflicting intervals so figured it would be best to do it early and be safe. Got the coils off the passenger side tonight-similar to drivers side where the rear coil is buried deep. Some fanangling got it out. Turbo inlet and heat shield removed to gain access to the coils Rear coil torx bolt...had to put the wobble extensions to use
And the coils are out. On this side there was not much play in the connector wires as they were tied into a loom that has a ground near each coil. Take your time and they will come out without removing the ground wire.
Ready to pull the plugs Coils-seem to be in good shape.
I wouldn’t do it initially by myself. If I had a “Porsche Buddy” where we could work together, and learn along the way, then perhaps. Luckily, I’m at 7500 mile so I should be good for a while.

While I'm pretty handy and have a ton of tools, this doesn't look like something that I want to attempt.
