Volvo penta spark plug selection

[rss221]

Putting a 2003 5.0GXI-B back together and I don't know the correct A/C spark plug to use. The Volvo # is 3858996. Is this the same as MR43TS or MR43lts.

I believe the MR43LTS is for the Vortec heads which your 2003 should have. The other one is for pre-Vortec.

Thanks, that is the marine version of the longer reach (11/16) plugs use on 1999 and later 305 truck engines. Which is what I used for reference.
