I have a 1992 OMC 4.3 V6
Was out the other night and one of my spark plugs blew apart. Replaced it with an old spark plug and continued on. Went out the next night and the same thing happened to a plug on a different cylinder. The boat recommends using AC Delco MR43T but I was running the R43TS. It was my understanding that its the same spark plug just not stainless steel.
Do I have a defective set of plugs? Are the plugs different by more than just the type of steel? Could there be something wrong with my engine? Has anyone else had any success or failure running the R43TS?
Any input would be great!
Thanks
