I suggest you pay to have it done.

It looks as if it can be done without removing the rear bumper, but there appears to be an intercooler removal (both sides) and heat shields and liners - this is where I am likely going to break something, thinking it should be lose, and then 'encouraging' it to come free, and ending up with x hundred dollar bill to replace whatever was damaged.. So I am on the fence.

I am not on the fence with respect to gapping the plugs - .026" if memory serves, and changing the oil, as it seems very difficult to break anything there.

Is there a less restrictive way to swap the coils/plugs that doesn't involve taking so much apart?
I would actually recommend you remove the bumper, not try and do it with the bumper on.... Yes, there is a lot of dissassembly... Wheels, wheel liners, taillights, bumper, intercooler & racks, heat shields... but then you have a clean shot at the coils and plugs.

It's not particularly difficult, just some work. And I don't think there is anything particularly tricky or anything your likely to break (with the one exception being over-tightening the taillight screws, which might break the tabs if they are not already broken...

Paying someone to do it is always an option. It doesn't always mean something won't get broken, but you might not hear about it, or you'll pay more as it 'was already broken'.

This approach gives me the satisfaction of actually doing it myself, however, with a significant downside as you note.

Do I at least have the plug gap correct?

Ironically, I am able to conduct this work on the gas jobbies with no issue - probably due to the increase in available space.

I suppose it makes more sense to send it to the shop; at the same time, the manual dipstick could be installed - I could only imagine what could (would) go wrong once I unbolted the engine to gain access...

Take the bumper and the pieces off. It's an easy 2hr job start to finish if you do that. Don't worry about gapping the plugs if you are using OEM plugs. They come pre-gapped so you can Install them out of the box and worry about other things like "where is the beer?".

I have never ever gapped the OEM plug on any of my engines, 3.6, 3.8, and 4.0. For engines running 1.3 bar or so OEM FR6LDC is all you need. I use OEM 996Cup plugs (FR5DTC) which are 1 step colder. Zero issues, ever.....

I could not get the Bosch OEM, so the alternative was an NGK Iridium BKR7EIX, so I want to check the gap as there is no guarantee it is correct.

I was not aware of the 996 Cup Plug number, am checking it now, thank you.

Cheers,

OEM Bosch or Beru is available just about anywhere on line or from any Porsche dealer.... Infinite supply... I would personally not run the single electrode NGK...

Yah remove the intercoolers and all. Once you have it cleared you can use an extension and swivel so you don't need small mitts.

Yes, I was trying to support my local guy - I'm looking for the Cup ones now.

Thanks, appreciated.

There you go. The triple electrode Bosch is fantastic. For a street application on a mostly stock street engine I'd probably stick to the range 6 OEM plug. Porsche did originally spec a range 5 on the GT2 however and later switched to a 6.

If you decide to do it yourself, which is very easy if you follow 2fcknfst's disassemble instructions, one advice I can give you is TRIPLE check all connectors to the coils are secured correctly.

You do not want to end up like me, and learning the hard way that after you put everything back together, one connector was not full secured back in place, and you start misfiring few miles down the road.

I really have no idea how people change plugs and coils without removing bumper, intercoolers, etc. I know I keep reading that it is doable, but I have no idea how.
