Overview Note: If installing the Blaster SS Coil to a points distributor or a non-current limiting ignition system without an MSD Ignition, a 0.8 ohm ballast resistor is required (MSD PN 8214). The resistor should wire in series along with any factory resistors on the positive coil wire. | Don't let the compact size of the Blaster SS Coil fool you, because it is packed with performance! The efficient E-core windings are designed to produce high amounts of current without sacrificing the voltage output. In fact, when used with an MSD 6 Series Ignition, the Blaster SS produces 300 milliamps of current and maximum voltage output of 40,000 volts! Universal - Add To Any MSD 6-Series Ignition Features Premium epoxy-filled, compact performance Blaster SS ignition coil from MSD Ignition! Compatible with MSD 6 & 7 series ignitions and electronic ignitions Tough, rigid housing with a tall tower and brass primary terminals 70:1 turns ratio and lower primary resistance produce high voltage output Efficient winding design and assembly creates a compact housing with powerful punch Primary and secondary windings are encased in Ciba polyurethane
