GM - Mid 1980s to 1990s Vehicles Equipped with 2-tower Coil Packs

MSD designed these Coils by combining our Blaster Coil experience with E-core coil efficiency. Each coil has a unique turns ratio plus there is lower primary resistance than the stock coil. This all amounts to a bolt-in replacement coil that produces more output voltage. The Coils will work with stock ignition systems as well as MSD equipped cars and trucks.
