Description
MSD Digital 6AL Ignition Control – Black
High-output digital capacitive discharge ignition featuring top-mounted rotary rev-limit adjustment and a sleek black cast-aluminum housing.
Product Overview
The MSD Digital 6AL Ignition Control (PN 64253) sets the benchmark for high-performance capacitive discharge ignition (CDI) systems. Re-engineered with updated digital microprocessors and high-efficiency circuitry, the Digital 6AL delivers over 530 Volts to the ignition coil with up to 135mJ of spark energy per firing while drawing less current from your vehicle’s electrical system.
MSD’s proven multi-spark series fires for 20 degrees of crankshaft rotation at lower RPMs to ensure complete fuel combustion, instant throttle response, smooth idling, and reliable high-RPM performance up to 15,000 RPM. Encased in a low-profile black cast-aluminum housing, all wiring exits through a single sealed locking connector for clean, simplified engine bay cable routing.
Key Features
- ☑ High-output Capacitive Discharge Ignition (CDI) providing 530V+ primary voltage and 135mJ spark energy.
- ☑ Top-mounted two-step rotary rev limiter adjustable in precise 100 RPM increments.
- ☑ Advanced digital microprocessor monitors every spark event for improved engine output and lower current draw.
- ☑ Multiple spark series fires across 20 degrees of crankshaft rotation for complete combustion.
