Hi all,
Pulled my plugs out last night. This car makes it very easy - the only thing i'll say is that you absolutely need an allen wrench-sized bit in a socket for the coil packs. I had to rig something up that worked, but if you don't attack those bolts with a ratchet you'll hate life.
Took me about 2 hours, most of which was simply lying on my back trying to line up coil pack bolts and get them in and out and torque'd.
Anyway, this was my father's car. He is great at keeping on top of maintenance, not so good at keeping good records. So I'm guessing these are not the original plugs (unless Porsche used "Beru Ultra").
Here's a pic:
Whaddya think? FYI, car ran absolutely fine before and after. One of those plugs was on a side with a bad o-ring/plug tube which is leaking a bit of oil.
