Ok, is AC Delco the same coil as the Delphi or a different brand that's similar? Also, which one is EFI connections referring to with the GM 12573190 stamp on it? I'm parting together parts for a 24x conversion and would like to know which one is better. Delphi coils I can find better price it looks like. Thanks
