So my manual has AC-R43T's listed. When I crank that number into my cross-reference guide I get Porsche plugs. Champion RV8C and Bosch WR4CC. I can get either one locally no problem, but I wanted to know if someone else has a different number before I go sticking plugs in that are listed in my software for a 1973 911 Porsche. Its not a marine database, so it doesn't list marine applications, just cross references the part number and gives you a list of cars a given part was commonly found in with a list of part numbers made by various companies that are interchangable.

Sooo..... Who is running what plugs in their SBC's?

ACDelco MR43T is the marinized version.

Jerry , is correct . Bosch plugs ( along with ND NGK ) don't seem to work well in SBC .

Yep, both statements above are correct. and spark plugs for a car, will rust and break just when you need the boat the most!!!

Looks like Summit has them. I guess I will get some sets when I order those 1409's.

I bought mine thru Summit when ordering some car parts. They had the best price I could find at the time.
