Put in new plugs last night...
On the left, new Bosch FR6LDC about to go in, gapped to ~0.034".
On the right, 28K mile Beru FR6LDU.
First time doing the job on a Turbo... Yup, you have to disassemble quite a bit to get to the coils and plugs, but once you figure it out it goes pretty quickly and the actual coil/plugs are a breeze.
Thanks to Kevin for his advice on plug type and gap.

the bosch and beru "Bosch FR-6-LDC , Beru 14 FR-6 LDU" (7410) are virtually indistinguishable from one another and are offen used interchangeably. though when "buying" everyone including kevin here prefers/recommends the "bosch" fr6ldc as a replacement.. and thats what i have always been advised ( and have ) used as well. good enough for gt2's,.. good enough.
the cars were originally released with a "5" heat range plug but they went hotter ( "6" ) for the next year of production so by 03 certainly.
tuned cars tend to burn up plugs faster than stock cars so while porsche recommends swapping plugs as part of a "major' ( vs minor ) service interval, i never wait 30k miles to change mine. more like 15k max and the car is always seemingly "brighter" and more responsive for having done so.
here you can see pelican even lists them "together"

Quite a bit of disassembly, but all easy...
No bolts were particularly difficult to get to, nothing required tiny hands, nothing required special tools. Once disassembled, the coil packs and spark plugs were pretty easy access.
Honestly I'll take a job like that any day over one that requires you to be a contortionist, or work in the blind, or need to ask for your wife's help because your hands won't fit!
Your also working primarily from the side rather than underneath, zero problem to do without a lift.
I had labor quotes from $700-$1,000 to do the job, which strikes me as absurd. Even doing it for the first time, I think it will take me no more than four or five hours including LOTS of time just figuring it out, sequentially tagging bolts, taking pictures, etc. I could probably do it a second time in half that.

Not to thread jack, but are there any upgraded cool packs that would be noteworthy when someone is changing out plugs and coils? Or are stockers adequate enough for higher than stock horsepower?

Yeah I can understand that. I haven't tackled anything that's required me to remove any bumpers yet.

Not a super big deal though as they can be had for under $40 each.
I too was a bit freaked out about removing bumpers. Sounded like a big deal... Had to remove the front a few weeks ago to replace my AC condensers, and the rear bumper yesterday, Absolutely no big deal.

The current rev OEM Beru coils are 997 coils...
997-602-104-02
The ones you pull out might be 996-602-102-00, but no longer available, superseded by the above.
