a plugs just a plug?

[floater212]

I have a 2005 rinker 212 with a 350 mpi, I am looking to replace the spark plugs BUT they are AC 41-932 which are hard to find around here. my problem is which plug should I use? I heard someone that said the ac 41-932 were replaced by ac 41-993, is this true or should I look for something else? any help out there? thanks, jim.:noidea:

I use the NGK equivalent, and Autozone have then, Summit racing have them. I use NGK ITR4A15 (5599)

(Mercruiser superseded the 41-932 to the NGK plug a few years ago... Here's a link to it at Summit) http://www.summitracing.com/dom/parts/ngk-5599/overview/

pretty sure the MR43T would work too. The platinum tip came along with the autos. nothing special about them except the cost.

Ayuh,.... Agreed,.... Nowhere in the service bulletin FT posted does it say the good ole MR43T, 'n for the Vortec heads, the MR43LTS Shouldn't be used,...

The MR43LTS IS the recommended service replacement plug on the later motors, Per the service bulletin,....

The Fancy, Expensive plugs gotta be re-gapped to work on the carbed motors,...
