My service manual lists the N-7 Champion plug.
My Hanes manual also lists the Nippon Denson W22EP and Motocraft AG12.
The others will work in a pinch but the consensus seems to be to stick with NGK or even upgrade to the NGK iridium bpr7eix.
New plug caps are required for the iridium switch. Caps are cheap. There are a few threads about the iridium upgrade.
