Replacing spark plugs.
Hey fellas.
Just wondering If anyone out there has a spark plug number for an 07 lsv with the assault 325 mpi engine. I have had the boat for 3 years so I am not sure when the were replaced last. Boat runs fine but just thinking about replacing them.
Thoughts?
Richard.

Replacing spark plugs.
Ok. I’m confused. The first one and the second on conflict with the CAT numbers. My engine is non cat. Or did I miss read that?

MR43LTS are standard plugs and 41-993 are iridium plugs for cat engines. AC Delco dropped their platinum plugs. I run Denso 4511 PT16TT Platinum TT in my 325 MPI. Good plug for a reasonable price.

Yes. I did not know the number that was dropped.
I found this same chart on the Supra and Mastercraft forum
