MSD Blaster 2 Ignition Coil for MSD 5/6/7 Series — Black, Oil-Filled High-Output 100:1

The MSD 82023 Blaster 2 is a high-output, oil-filled ignition coil engineered to deliver stronger spark energy for MSD 5, 6 and 7 series ignition systems and compatible electronic or points-based ignitions.

This compact black Blaster 2 coil from MSD is built for performance applications where consistent, high-voltage output matters. Its oil-filled canister construction and alkyd tower reduce carbon tracking while a 100:1 turns ratio and optimized primary resistance increase secondary voltage. The coil is CARB E.O. approved for street use and is commonly used in street, strip and track engines that require dependable ignition energy.

How does the Blaster 2 improve ignition performance?

The Blaster 2 raises secondary voltage and delivers a stronger spark window compared with many stock coils. That translates to more reliable combustion under heavy load, higher RPM, or with boosted/fuel-injected setups that demand consistent spark energy.

• 100:1 turns ratio to boost secondary voltage.
• Lower primary resistance for faster coil saturation and stronger output.
• Oil-filled canister for improved heat dissipation and stable performance.
• Alkyd tower reduces carbon tracking and misfire risk.

Which ignition systems is this coil compatible with?

The MSD 82023 is designed to work directly with MSD 5, 6 and 7 series ignitions and also supports many electronic and points-based ignition setups. For points applications, a ballast resistor is required; check system specs for wiring and resistor needs.

• Direct compatibility: MSD 5, 6 & 7 series ignitions.
• Works with electronic ignitions when wiring matches coil specs.
• Points-style ignitions supported (ballast resistor required).
• Suitable for street and track installations—CARB E.O. approved.

What are the key design features and why do they matter?

The coil’s oil-filled canister, alkyd tower, and calibrated electrical characteristics are all chosen to maximize spark reliability while minimizing failure modes like carbon tracking or overheating. Those design choices help maintain performance in demanding environments.

• Oil-fill: stabilizes temperature and extends coil life under load.
• Alkyd tower: high dielectric strength resists carbon tracking and arcing.
• Optimized turns ratio and resistance: better voltage output and faster recharge.
• Black finish: corrosion-resistant, OEM-friendly appearance.

How easy is installation and what should I check before fitting?

Installation is straightforward for mechanically skilled enthusiasts and professional tuners; the coil mounts in common bracket locations and connects to existing ignition wiring. Verify tower alignment, dwell control, and whether a ballast resistor is necessary for your ignition type.

• Mounts in standard coil brackets with two-bolt footprint.
• Confirm correct primary wiring and polarity for MSD systems.
• Use a ballast resistor for points ignitions as required.
• Inspect high-tension lead routing and boot condition for best results.

Who is this for: The MSD 82023 Blaster 2 suits performance-minded drivers, tuners, and racers who need a dependable upgrade to factory coils—especially those running MSD 5/6/7 series ignitions or high-demand engines. It’s a practical choice for street-driven performance cars, weekend racers, and anyone upgrading ignition components to reduce misfires and improve throttle response without complex control systems.
