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.
Product Features
- 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
Not for horizontal mounts. I needed it since my accel was leaking and causing my truck to stall. The problem I have with this MSD coil is that it’s supposed to be a “direct” fit for my 1970 F-250 which has a horizontally mounted coil but the MSD instructions say this coil is for vertical mounting only. MSD makes a coil specifically designed for horizontal applications.
Made a noticable difference. Direct replacement for factory unit on 1989 Subaru GL10 Turbo. Definitely noticed a power increase.
Four Stars Can’t beat the Blaster 2 for a CD Electronic Ignition System.
