The one in the toolkit is up to the job. But...
I made my own tool for the front two cylinders, where accessibility is minimal and a regular plug wrench is not ideal. I bought a short 16mm socket and shaved off two sides on a bench grinder. I could then pop it in and attach it to the notorious 1B spark plug end, which was then removed with a regular spanner.
Alternatively, you could get a socket with a hex end, which is already designed for this type of use:
(similar to the pic above, but shorter)
Pics of my home-made tool:
(note: I ground it down further after this pic, so I could use a smaller-sized spanner than the biggish 21mm)
Oh, and do gap those new spark plugs before you install them, I've had a few that were substantially off-spec when I unboxed them...
JLM1909 is not available any more, SNG Barret
only offers an aftermarket reproduction part, is that ok?
It is of slightly lower quality than OEM, but it's basically the only part you will be able to find...
The OEM part has been out of stock for ages, chances that you will find a NOS part are close to zero.
And while I'm at it: some pics of my ex-DD6's ignition components, illustrating why these things need TLC.
Check those burn marks!
