MSD Blaster SS Ignition Coil Black 40,000V 300mA 6.9mH Inductance 82073

A weak spark kills performance. The MSD Blaster SS Ignition Coil delivers 40,000 volts and 300mA of current through an efficient E-core design, ensuring a hot, reliable spark that translates to faster combustion, quicker throttle response, and stronger overall engine output—especially critical when running high-compression builds or forced induction setups. Built with Ciba polyurethane encapsulation and brass primary terminals, it's engineered to withstand the heat and vibration of sustained high-RPM operation without degradation.

If you're running an MSD 6 Series ignition system and want to maximize spark intensity and consistency across the RPM band, this is a direct bolt-on upgrade that delivers measurable gains.
