I tried searching the forum but couldnt find any info. Looking for spark plug recommendations for my crusader model 350? i believe champion rv8c are correct but im not positive. any suggestion on a "quality" plug even if its a different brand?
Thanks

The owner of the boat I work on uses the AC Delco MR43T. They are a touch cooler than the spec plug, but apparently it is better for slow speed trolling. I think the spec is MR44T.

IMO, I think you will not see much difference in performance or reliability between any of the major brands (NKG, Champion, Delco, etc).

Smart move the AC is a better plug for a GM engine

1995 Crusader 454XL takes Champion RV8C. I have used NGK and never notice any difference. The Champion are Stainless steel as NGK are not
