Cross reference plugs on Mercruiser 4.3

[brianwhart]

I've got a 1997 Mercruiser 4.3 S/N 0L128007 and I'm trying to figure out what NGK or Champion plugs I need to run in it. Right now I believe it has AC Delco plugs model AC-MR43LTS, according to the top of the flame arrestor. Does anybody know how to cross reference these plugs and tell me what model Champion and/or NGK I should get? Thanks.

Don't even Think about Champions.......<br /><br />Those ACs are about the Best Plugs for that motor there are........<br />The "S" stands for Stainless Steel bodies......
