Spark plug adapter

I need an adapter for my compression tester to fit the larger sparkplug holes. Can any one tell me the specs that I need to look for?

A google search provide the wrong spec and I ended up buying one the doesn't fit. ...should have asked you guys first.

Thanks!

Snyders has a spark plug adapter that I use with my Snap-On compression tester. https://www.snydersantiqueauto.com/s...ht=a-12405-adp But like numerous things these days, I see they are "Temporarily Out of stock".

I punch out the porcelain center of an OLD spark plug. I us a compression tester with a rubber tip.

Good idea - if I had an old sparkplug. I'll keep that in mind.
