Sniper spark plugs

[Brewbro21]

Could find any info. So I’ll just ask…what spark plugs are you guys running with your Holley Sniper system??

Also what plugs are you guys running in general wether you have original ignition system or MSD, etc?

Back to the top for this too. I don't remember seeing talk of changing plugs necessarily for the induction setup. Just the different plug recommendations in general. If I remember the discussions of old, our engines do seem to like good old Autolite copper plugs rather than the modern fancy platinunobtanium tipped versions. But I have not heard much talk of any of the new-new plugs being preferred or even tested yet.

My Bronco with Sniper EFI runs best with the cheap copper Autolite 25's that Paul mentioned. As for plug wires, MSD 8.5mm Super Conductor wires work great

Whatever plugs the engine would normally use.
Gap is based on ignition used and a little on the compression ratio. A more powerful ignition you run something in the lower 0.040" range, breaker point ignition it is in the upper 0.020" range. If there is a lot of cylinder pressure you are trying to pass the spark through, a little less gap. Not so much cylinder pressure you go a little larger.
