MSD 6201 Digital 6A Ignition RED SKU: 6601

MSD Digital 6A Ignition Control | Red | #6201

For decades, the MSD 6A Ignition Control has been the go-to choice for builders who want serious spark performance without unnecessary frills. Now redesigned and updated, the Digital 6A delivers even more ignition power and efficiency in a refined, compact package. Whether you're firing up a street machine, trail rig, or classic muscle car, this ignition box provides cleaner wiring, higher output, and more reliable spark energy—all in the legendary MSD red housing.

The Digital 6A uses advanced microprocessor technology to monitor and control every firing cycle, delivering up to 135mJ of spark energy and 530+ volts to the coil, while drawing less current than older designs. The result? Better throttle response, stronger combustion, and smoother performance across the RPM range. The sealed, locking connector and side-exit wiring make installation neat and straightforward. No built-in rev limiter—just pure, consistent spark for 4, 6, or 8-cylinder engines.

• High-Output Spark: Generates 530–540 volts primary, 45,000 volts secondary, and 135–145 mJ per spark for reliable combustion.

• Digital Efficiency: Updated internal circuitry draws less current while producing more energy.

• Multiple Spark Series: Delivers multiple sparks per firing below 3,000 RPM for cleaner combustion and improved idle.

• Built-in LED Indicator: Allows for quick diagnostics and system checks.

• Neat Installation: All wires exit from a sealed, single-side connector for a clean engine bay layout.

• No Rev Limiter: This version is designed without an internal rev limiter, ideal for users with external control systems.

• Wide Compatibility: Works with breaker points, magnetic pickups, and amplifier-style distributors.

• Vehicle Fitment: Compatible with 4-, 6-, and 8-cylinder engines running 12V negative-ground systems.

• Street Legal: CARB certified under E.O. #D-40-43 for use in all 50 states, including California.
