Some interesting points, Jim.

 

After reading Paul Yaws experiment with sparkplug and the possibility of

some brands extending into the combustion chamber and clipping apex seals -

I have not been inclined to experiment.

 

I’m wondering if anyone using unshrouded plugs (such as the NGK - B9EGV) has experienced the SAG effect.
