what are you supercharge guys running for spark plugs and what are they gapped too?
Thanks.
Thanks.
I am running ZFR7F gapped to .028-.030
and you wonder why it's not running
Planning on pulling and inspecting mine this weekend. Will post what I have when I do.
you aren't supposed to break them
Those "speckles" would concern me, isn't that a sign of pre ignition? I run Bosch 7927 on my Roe supercharged SRT Ram and supercharged Viper GTS..032 I believe is what I run. Hard to tell from the pic, but yours looks closed up significantly.
