What are your thoughts on shaved electrodes?

and gaps? bigger smaller?

ive always run stock gap on -11 plugs.. but just bought 7es-11's and gapped em at 28 in my Z on 23 psi. runs good.. but better on bigger gap or shaved electrodes?

just curious on your thoughts thanks.

well, ive ran gapped down plugs, i've never had good luck with shaved electrodes.

i just run the bkr7eix 's and gap them to .028 - .030
