The blaster coils share the same special windings and high voltage output but do not include a ballast resistor. When you are using an MSD Ignition control, the ignition is responsible for delivering the voltage to the coil so a ballast resistor is not necessary.
- Low resistance and improved turns ratio produces a powerful spark for improved performance
- Special windings and high voltage output; does not include a ballast resistor
- Sturdy metal housing is finished in red
- OBD II and CARB approved; legal for use in all states; D-40-37
