So I am trying to find out about switching to MSD ignition coils. It seems that there is no clear listing since there were two kinds used. The normal Delco units and a Melco-Mitsubishi unit. If you look up the part for a 2010 6.2L L99 Camaro, two part numbers show up with no distinction for application differences. One, the GM, starts with 125 and the other starts with 126. If anyone knows the correct MSD number or the correct stock number OR has any clue as to the right coils, please lmk. Thanks all.
