the factory tool is the only way to go. I used NKG plugs once, which have are 5/8" hex and changing them out made me go back to Bosch and the 13/16" and the factory tool. I had to use a 5/8th spark plug socket with the swivel but i had to tape it up to take the slop out of the swivel and i really could not get the extension to the right length to make it as simple as the factory tool

I did this with my local 930 bud on his 87 and found, that like on my 82 SC, the best tool is an old school pressed metal plug socket snagged from a 70's BMW tool kit. Easier for me than the 911/Klein plug tool. John.

Factory tool, and have to remove waste gate for bottom row on my twin plug motor. No emissions, or air box and remove IC. Takes me about 45 minutes start to finish.

I use basically the same thing. but I actually welded it all together.
I also have the factory tool, I prefer mine.

not sure what all you have on your engine that is in your way.
#1 is the hard one for me.

I have also done compression, leakdown and just recently put a colortune in all 6 to check mixture. going to do it again.
yea I get a little scratched on the left side. I could make it easier if I tool the IC off.
getting lazy(ier)

The tough one was #3. It hides under the paper heater tube. I was afraid I would lose the plug in the hole, or not be able to get the new plug started and wind up pulling the engine.
Now that the CV joints boots are failing, I might pull it anyway.

does you sparkplug socket have foam inside to hold the plug?
also why I welded my socket, swivel and extension together.

I use the engine drop method. Jack up the car, remove the tires, remove the rear engine mount bolts, lower the engine a few inches and they are easy to get to.

I have to take the intercooler off for the 6 plugs on top, jack up and the wheels off for the 6 plugs on the bottom.
but I have noticed as I get older my patience is getting less. Not a bad job but I plan for at least an hour or more to do it.

Changed plugs again on a Euro 930. These are the only tools you need to do the job. It helps to have the plug socket pinned so the adapter doesn't pull out when putting in the new plugs.

Must not invoke images of Rawknees changing his "plug" in his 930.

Maybe a little crude Alan,

However works perfectly.

Nut weld to socket, then bolt weld to nut.

That nut/bolt thing must be the perfect length. Otherwise to tall to fit in some of the plug apertures and if shorter - can't get socket on. Thanks.
Brian - that is pretty much what I have right now. How are you pinning the extension - that is the issue I have - sometimes won't all come out as a unit.
Regards
Alan

By the time you've "taken off all the crap that's in the way" I'm having a post-plug-change beer.

Hey Norm, by "drop" I was referring to "removing" the engine. That's what I thought the original post was talking about.
Yeah, dropping just a few inches makes a world of difference. Wish I had the proper Porsche tool instead of a menagerie of extensions, though.

Yes, I thought 'Drop' meant 'remove' also. But it is perfectly do-able without either.
I see Pelican have the Porsche tool listed - $105 approx..
By the time I pay airfreight etc it will turn out to be $200 by the time it gets here.

I found I was able to wind the bolt in until I got the best length. So some cylinders I used a socket and wrench, and mainly no. 1 used a rachet spanner.
With IC removed and air cond compressor moved to the left.

You don't need the factory tool. Pin the adapter to the socket like shown above and that is the only tool needed for all 6 cylinders. We have access to any tool we need and can make those we don't and this is what we use. Extremely simple and effective.

Brian - how do you pin the plug tool to the extension. I would imagine you are drilling in to hardened steel?

Not necessarily, you can use cheap tools that are easier to drill into sense the torque setting of a spark plug is so low.
