Want to replace the plugs in my 2004 Mercruiser 5.0 MPI. Currently have AC Delco 41-932. Called my local auto part store and they advised that they only have two left and can't get anymore because they were discontinued and replaced by plug # 41-993.
Last time I bought something at this store they got it totally messed up and so I don't really trust them anymore. Can anyone confirm if 41-932 was superceded by 41-993?
