A very timely question for me. A month ago I installed 4 new MSD coils and got 8 misfiring plugs. A switch back to OE Delco works fine. The MSD were made in.....China (No!!!!). Advice to myself: dont swap for the sake of 'not having to go under there again' (you will regardless and get used to it) and if you have a problem with coils, use OE parts.
