spark plug cap size

Post by Simonpsmith »

Have just bought Champion D9 spark plug - but the current plug cap (LB05EH) doesn't fit as the spark plug is wider than the old one.
I could use a spade end fitting but would like to know if there's a plug cap that fits?

The plug is missing it's screw-on terminal!

answered my own question:

None of the NGK plugs caps fit the Champion D9’s.

But these do:
