    MSD Ignition 6425 - MSD Digital 6AL/6A and 6-Series Ignition Control Boxes Details

    6-Series Digital Ignition Controls

    MSD's Digital 6AL Ignition has the same footprint as the original 6AL yet incorporates a sleeker, lower profile and relocated rev limiter. The limiter is on top of the housing for easy access to the two rotary dials that control the rev limit in 100 RPM increments. To simplify installation and keep things tidy, all wiring is routed out one end of the ignition box through a sealed connector. Inside the Digital 6AL Ignition, a microprocessor manages and monitors every firing while high-efficiency circuits make more power using less current.

    Features
  • Compatible on 4, 6, or 8-cylinder engines with 12-volt negative ground electrical systems
  • Same bolt pattern as traditional 6AL but with low-profile housing
  • Delivers 530 volts to the coil with up to 135mJ of spark energy per firing
  • Efficient internals draw less current to produce more power
  • Set rev limit in 100 RPM increments with two rotary dials
  • All wires exit on same side via sealed/locked connector
  • Accepts trigger inputs from breaker points, amplifiers, and magnetic pickups
  • Includes wiring harness, necessary installation components, and vibration mounts
  • Built-in LED for system checks
