Quote from Larry Engelbert (Indmar Marine Engines)
If your engine dose not have catalytic converter exhaust, I would recommend using conventional AC/Delco MR43LTS plugs gapped at .045.. Any catalyst engines should use platinum or iridium plugs. The plugs we used in the cat 5.7L engines have superseded to 41-101 gapped at .040.
