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.
Direct performance replacement for GM 2 Tower coils used from the mid 1980’s to late 1990’s
80:1 turns ratio and lower primary resistance produce high voltage output
Works with stock ignition as well as MSD Ignitions
