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

Built to deliver stronger secondary voltage and improved combustion consistency, the MSD Blaster 2 coil in black is engineered for street and track use. Its oil-filled canister and specialized alkyd tower reduce electrical tracking and support reliable performance in both stock and modified engines. The coil’s 100:1 turn ratio and optimized primary resistance are tuned to work with MSD ignition units while remaining compatible with many electronic ignitions and points systems (points installations require a ballast resistor).

How does this coil improve ignition performance?

The Blaster 2 produces higher voltage at the plug by coupling a low primary resistance with a high turns ratio, which helps the ignition system fire more consistently under load. That stronger spark can improve combustion stability and throttle response without changing engine tuning.

• 100:1 turns ratio for elevated secondary voltage
• Lower primary resistance to increase spark energy
• Oil-filled canister for consistent internal insulation and heat dissipation

Will the MSD 82023 fit my ignition setup?

The Blaster 2 is designed to pair directly with MSD 6- and 7-series ignition boxes but will also function with many aftermarket electronic ignition systems. If your vehicle uses breaker points, you must use a ballast resistor to prevent overcurrent; otherwise it installs like a conventional coil.

• Direct compatibility with MSD 6- and 7-series units
• Works with most electronic ignitions without modification
• Requires ballast resistor when used with points-style distributors

Is the Blaster 2 durable enough for street and track?

Yes — the oil-filled canister and alkyd high-dielectric tower are built to resist carbon tracking and handle elevated temperatures. The coil meets street-legal standards while offering the robustness enthusiasts expect for occasional track use.

• Oil-filled construction improves insulation longevity
• Alkyd tower reduces arcing and carbon tracking
• CARB E.O. approved for street legality where applicable

What installation considerations should I know?

Mount the coil in a vibration-secure location with adequate cooling and use correct wire gauges for both primary and secondary connections. Observe polarity and follow MSD wiring recommendations; for points systems, include the correct ballast resistor to protect the points and coil.

• Secure mount to minimize vibration stress
• Use recommended wire sizes and MSD-approved connectors
• Include ballast resistor for points-style distributors

Who is this for: The MSD 82023 Blaster 2 coil is aimed at drivers and tuners who want increased spark energy without complicated modifications. It suits street-performance builds, classic cars upgraded with electronic ignitions, and weekend racers who need a reliable, CARB-compliant coil that pairs seamlessly with MSD ignition boxes or many aftermarket systems.
