A couple points:

1) It's definitely NOT the 3/8 socket. That one fits my Audi, but alas, not my 944. 13/16 should do it. That was a special trip to sears for me. Fun.

2) The wires will last quite a while, but after 19 years, mine were toast. The cheapest set of ignition wires I found was from Vertex, using a monthly special ad I saw in Panorama. I think they were only like 90 bucks for OEM Beru, ready to install, and included the distributor wire.

3) The cheapest and best plugs are single electrode copper. As long as you are in the right heat range, you should be fine, not to mention you can get 3 or 4 for the cost of one platinum+4. Stock in my 8v was Bosch WR7DC.

Of course, YMMV...

Edit: Thanks for the new sig material P-O-P!

With the S2 your plugs WILL be deep in a hole... get the "real" plug wrench with the rubber insert! If you have an air source, be sure to blow out any crap that may be down in beside them (Even with the nice plug-wire seals there always seems to be a little crud down in there).

If you've got the original tool kit there is a plug spanner in there (but from memory no rubber insert) - or at least there is according to the book.

I've never checked whether mine fits though.

Very good advice. I usually just loosen the plug a bit, then blow air with a thin nozzle. Believe it or not I know of one P-car that had an old metal washer down in the recess. The plug was pulled, he heard a plink, and guess where it fell? Luckily he was able to fish it out with a magnet. I always check now. I also put thin coating of hi-temp anti-sieze on the plug threads as well as dielectric grease on the plug boots.

You can actually buy spark plug wire pullers. Great idea as they get hard to remove with time. Otherwise let me 4th or 5th the recommendation for NGK or Bosch coppers.

what is the gap meaurement for a 951? And what if you dont have a torque wrench......do u really need one?

Matt H

I have the gap somewhere (you can search the turbo board) but I do it without a torque wrench all the time.

its a 1/4 turn after hand tighten, i always do that. its not worth busting out the torque wrench for that. in fact on the bottom of you bosch box it will tell you that as well, my last 4 did

iloveporsches

Just don't use Indiana torque specs:

Turn until stripped, and then back out 1/4 turn.

I always use a torque wrench for my spark plugs.
PO of my 86 stripped all 4, made me really paranoid.

Bosch single-electrode copper, or Champion copper's.
There is no measurable benefit of running anything more, at least not that I have seen any proof to.
20lb/ft (as already said) on a 13/16" spark plug socket is just fine.
I prefer to change them on a cold engine for obvious reasons.

Now, go forth and multiply... err... change plugs.

Andial951

OK....for those of us without engineering degrees and who didnt do our college thesis on spark plugs.....if I walk into my local auto-parts store and ask for single electrode, copper Bosch plugs.....will I get what I need? Is there a specific plug number?

zoltan944

the # is on your sticker in your engine bay, but they don't work like that. So:
autozone:can i help you?
you:i need spark plugs for my 19** porsche 944
autozone:which of these 9trillion ones would you like, and they will automatically point to the bosch single electrode platinum plugs, for about $2 a peice 9cause they are OEM replacments)
you: No, the Bosch 'Supers' for $1.22 will be great

they will get you 4 and the # will prolly be WR7DC
the turbo may be different #

mavfan

that is a perfect writup. someone should post that on clarks-garage.com lol now it wasn't that difficult now was it? and i would have never have thought to usea torque wrench on the plugs, just dont be stupid and you'll be ok!

Blue S2, For your 944S2 you will want to buy NGK BPR6ES / Champion RN7YC / Bosch WR5DC

You can pick your preferance out of those 3 sparkplugs since it really makes little to no diffrence. All other plugs you find at a parts store are 100% Garbage expecially the Bosch Platinums and all Iridium Plugs.

P.S. When you install your sparkplugs using the 13/16 Sparkplug Socket make sure you tighten them all the way. Working at a shop I cannot tell you how many times I see when people change there own plugs that they don't squash the sealing rings on the sparkplugs and the plugs become loose.

Here's a little tip if you ever find yourself without a plug wrench with the rubber insert thing. Take a regular deep socket of the correct size of course, and apply a small piece of electrical tape lengthwise down the outside of the socket and tuck about a 1/2" of the tape back inside the socket. Take a new plug and fit it in the socket by hand to check the fit (sometimes more or less tape is required, but one thickness and width is usually fine. It will usually fit nice and snug and stay in the socket nicely when removing or installing inset plugs. I think I have even done this to start bolts that you can barely see, let alone reach.
Best of luck.
