I'm going to do a spark plug and fuel filter change this month, should I be concerned with the fuel accumulator? I'd like to save the most expensive fixes for last, if the minor fixes don't resolve the issue.

Remember to use the spark plug wrench provided by Porsche. It should be in a tool kit nestled up against or in front of your spare tire. The shape of one of the heads (don't recall if #1 or #6) makes it near impossible to pull the plug out when it is in a conventional wrench.

I have the original toolkit that looks like it's never been used, but I thought that I wasn't supposed to use it as it was valuable or something.

Let's put it this way..... I have 32 sets of metric sockets in the top drawer of my 54" toolbox. I have at least a half dozen spark plug sockets from makers like Snap On, Blackhawk, Craftsman, Mac, Hazet, Williams......and none of them will extract that one plug. They make it in and can loosen it, but the shape and wall thickness is a bit too thick to worm it out.
The factory tool kit is there to be used. Well, at least the spark plug socket and the alternator pully wrenches are.

You may be able to use a regular spark plug socket (different ones may have different thicknesses), but like Amber and Ice say, the Porsche tool is far superior and designed for this particular application. With a regular socket being tight as Amber mentioned, you will likely have the extension you added to the socket pull out leaving the socket and plug still in the engine. I think it was cylinder 6 that was the tricky one... but my car is an '86 so it may be different.
If you don't have the Porsche tool, JB weld your extension (3-4" extension, not bigger or you won't have room in the engine bay to pull it out) to the spark plug socket. This way when you pull it out of the tight space it won't leave the socket behind. It is now your 911 spark plug tool! Having said that, if it's really tight, then your socket is too large in diameter and you shouldn't force it. Like I said, my advice is based on my experience changing the plugs on my '86... I'm not sure how different the '74 is for this job.
Also, buy the Bentley manual. Best investment you will make.
Finally, when you get them out, put them on a piece of paper and label which cylinder each one came out of. Then take pics and post them here, the people on the forum will be able to help tell you if the plugs indicate any issues.

I'm not sure on the gap... will check my Bentley when I get home. Also, buy the Bentley manual. Best investment you will make.

This is odd..
I'm pretty sure I'm using the right tool out of the kit(the one on the far left), but it seems I can't reach any of the plugs with the tool? Or do I need to remove the valve covers?

Why the hell is it that cylinders 1-3 were easy to pull out, and 4-6 are torqued to all hell, to the point that I can't even do this with my hands and the factory too???

Iceman, the plugs you referenced are no longer available as far as I can tell. That old numbering system is longer available. I can't find the crossover reference tables, but I think the W230T30 crosses to a W5d plug in the new listings. If anyone has any cross reference data, please provide a site.
