The Electro-motive does have the ignitors built in. I have been using the Bosche triple ignitors for years with no problems. I do like the MSd coils. I have used the Accel coils and stock replacement GM type coils as well. None of them have ever presented a problem.
How bout a link to M&S for their coils.
