It's the space between the inner and outer electrode, where you'll see nothing but air

Or hopefully sparks if there’s any of that there elastic trickery going though it.

True but you're going to need a small head to fit inside the cylinders and see if there's any of that Lucas trickery @ play

0.8mm will be fine

I think the Haynes says 0.8mm to 0.9mm but they can open slightly with use.

Thanks for that. I ended up pulling all 3 out and they looked new. I decided to put them back in as the PO changed them out recently.
