And make triple sure the wrench will retain a lose plug, and not drop it inside the sheet metal.

It is sort of like the factory part. I like the factory part coupled with the supplied Allen wrench. Gets into tight spaces, and I have the racket version of the Allen wrench.


I'm not sure about the exact 914 supplied item, but the one I have is just a 6-7" pipe with the correct socket opening pressed on one side. There is NO rubber insert and you have to fit a screwdriver into a hole on the side to get it to turn. Again, a sloppy solution imho. Yours may be better - I have seen some that are similar to what I posted above.. Klein tools maybe, but I assumed they were 911 items.

Yeah. From my 911. Sorry. Factory part was misleading.

Just use a socket and extension, you should be torquing the plugs with aluminium heads.

The spark plug socket I have, which is from a Kamasa Tools socket set, works fine on cylinders 1, 2 and 4 but won’t engage the plug on cylinder 3. There seems to be some part of the cylinder head that snags on the socket preventing it from sliding all the way down over the plug. I guess I need a thinner walled socket or to file away the outer wall of the socket enough for it to clear the obstruction. Anyone else have this issue?
Mine is a 1.7/1.8 litre type head.

That is a REALLY weird problem, and I suspect you have something else going on.
#3 is one of the easiest plugs to get to. #2 is always the hardest plug, followed by #1 - the two deep ones.

If #3 is stuck, I would guess its rusted in place or cross threaded. Spraying penetrating oil down there will help either of those. If its badly cross threaded you will want to fix the head before you jam another plug down there.

Is that not a temperature sensor wire/ring sitting under the #3 plug (they are usually under #3 when used), that's fouling your socket? - yeah a thin stock type socket would probably be helpful in that case.
