    MSD Ignition 4573 - MSD Blaster Coil Details

    Tower Blaster Coils

    The MSD Motorcycle coil is specially designed to be used with MSD's MC-1, MC-2, MC-3 and MC-4 ignitions. The Blaster coil uses a high turns ratio with low primary side resistance producing the highest voltage and spark energy available. The molded-in socket style towers are spaced far apart to prevent arc-over.

    MSD Ignition 4573 - MSD Blaster Coil

    If looking to upgrade your stock coil or to complement the performance of your MSD Blaster Ignition or MSD 5, 6, or 7, the Blaster Coil line is the right choice. All Blaster Coils are designed to improve spark output. Special 100:1 windings are used to provide maximum build-up of voltage; they're held secure and kept cool in an oil-filled metal canister. 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. There are several versions of the Blaster Coil available. All of them have the same internal specifications but different housings or components. Each Blaster Coil can be used with a stock ignition; Blaster Ignition; and MSD 5, 6, or 7 Ignition Control. Most late model vehicles with electronic ignitions do not require a ballast resistor (check your ignition and manufacturer specifications to determine if a ballast is required for your application).
