Details

If you are looking to upgrade your stock coil, or want to compliment the performance of your MSD ignition, the Blaster Coil line is the right choice. Special 100:1 windings, kept cool in an oil filled metal canister, are used to provide maximum build-up of voltage.  The tower assembly is molded of durable alkyd material due to its high dielectric characteristics while wide spaced brass primary terminals prevent the possibility of spark. Can be used with a stock ignition, Blaster Ignition, or MSD 5, 6 or 7 Ignition Control.

The 0.8 ohm ballast resistor must be used with stock points ignition and Mallory Unilite applications. Includes MSD Power Tower top.
