It's kind of funny/interesting the first sentence says "Easy mod that makes the MSD coil packs worthless."

However I don't really agree with that. This mod doesn't give you individual cylinder ignition control or boost ignition voltage, it just gives you a little more modern ignition setup. But it is a good solution for those running EJ20 engines & manifolds that were COP.
