MSD Blaster 2 Ignition Coil — 82023 Black for MSD 5/6/7 Series, High-Output Oil-Filled

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 systems and many electronic or points-based ignitions.

This Blaster 2 coil combines proven internal design with rugged external parts to produce higher secondary voltage and reliable performance under street and track conditions. Housed in a black canister and featuring an alkyd insulated tower, it resists carbon tracking and electrical leakage while remaining compatible with a broad range of MSD and aftermarket ignition boxes. It’s a direct-fit option for tuners who want a straightforward coil upgrade that stays street-legal.

How does the Blaster 2 improve spark performance?

The 82023’s design emphasizes higher secondary voltage and stable operation across rpm ranges, which helps ignition systems produce stronger sparks. Its 100:1 turns ratio and low primary resistance allow the coil to build and release more energy each discharge without needing complex setup changes.

• 100:1 turns ratio for increased voltage output
• Lower primary resistance for quicker energy build-up
• Oil-filled canister dampens internal arcing and heat

Is this coil compatible with my ignition setup?

The MSD 82023 is made for MSD 5, 6 and 7 series ignition boxes and also works with many electronic or traditional points ignitions. If your vehicle uses points, add a ballast resistor as required; otherwise, it typically plugs into aftermarket boxes without extra components.

• Direct compatibility with MSD 5, 6 & 7 series units
• Works with electronic ignitions and with points if a ballast resistor is used
• Common replacement for street and performance applications

What construction features help reliability and safety?

The coil uses an alkyd-insulated tower to reduce carbon tracking and prolong life, while oil filling helps manage heat and suppress internal arcing. The robust external shell and quality electrical connections make it suitable for repeated high-energy discharges during spirited driving or racing use.

• Alkyd tower provides high dielectric strength and reduced tracking
• Oil-filled interior for thermal stability and quieter operation
• Durable black canister designed for automotive environments

Is the Blaster 2 legal for street use and safe for track days?

The 82023 carries CARB Executive Order (E.O.) approval for street legality where applicable, and its construction supports track conditions when paired with compatible ignition components. As with any ignition component, install per manufacturer instructions and verify compatibility with your vehicle’s emission and ignition systems.

• Street-legal where CARB E.O. applies
• Track-capable when installed with proper ignition hardware
• Follow MSD installation guidance to maintain compliance

Who is this for: The MSD 82023 Blaster 2 coil is aimed at enthusiasts, mechanics and performance builders seeking a proven, high-output replacement coil for MSD 5/6/7 systems or for upgrading electronic and points ignitions. It’s a practical choice for street-driven performance cars, weekend track cars, and anyone who wants a durable, higher-voltage coil without complex electronics or extensive rewiring.
