MSD 8202 Blaster 2 Ignition Coil
(Part #5478202)
                        

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.

For use with stock or MSD electronic ignitions. Most late model vehicles with electronic ignitions do not require a ballast resistor, check your ignition and manufacturers specifications to determine if a ballast is required in your application.

  • Improved output coil for stock points or electronic ignitions, Blaster Ignition, or MSD 5, 6, and 7 Series
  • Supplied with two plug wire boots, terminals, and jumper wire
  • 100:1 turns ratio and lower primary resistance produce high voltage output
  • MSD Red metal canister is filled with a premium grade oil for cooling
  • CARB E.O. Approved
