Overview This Blaster Coil is supplied with a ballast resistor. If your application uses a points distributor, the ballast must be used. Late-model electronic ignitions or an MSD Ignition do not require the ballast. | If you are looking to upgrade your stock coil, or want to compliment the performance of your MSD Blaster Ignition, MSD 5, 6, or 7, the Blaster Coil line is the right choice. Our Blaster Coils are designed for improved spark output! Special 100:1 windings are used to provide maximum build-up of voltage! These windings are held secure and kept cool in an oil-filled metal canister. CARB EO: D-40-37 Features MSD Red metal canister is filled with a premium grade oil for cooling Improved output coil for stock points or electronic ignitions, Blaster Ignition or MSD 5, 6, and 7 Series 100:1 turns ratio and lower primary resistance produce high voltage output CARB E.O. Approved Supplied with two spark plug wire boots, terminals and a ballast resistor (required if used with stock points ignition)
