MSD 8223 Blaster 3 Coil


  • Upgrade your stock canister coil
  • Extra tall secondary tower
  • Improved output coil for electronic ignitions
  • High voltage output
SKU: MSD8223 Category:

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.

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. Each Blaster Coil can be used with a stock ignition, Blaster Ignition, MSD 5, 6 or 7 Ignition Control.

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. Mallory Unilite applications also require the ballast resistor.
