NEW MSD DIGITAL DIGITAL 6AL IGNITION CONTROL BOX WITH REV LIMITER,RED,520-540V,11,000 RPM RANGE,8"L X 4"W X 1.825"H,COMPATIBLE WITH 4-6-8 CYLINDER

Brand New MSD Digital 6AL Ignition Control Box with Built-In Rev Limiter, 520-540 Volts, Compatible with 4,6 & 8 Cylinder Engines, Produced by Holley Performance Products (Part #6425)
The MSD 6AL Ignition Control set the standards that other ignitions strive to reach. In fact, you will find ignitions from other companies that carry the 6AL name (and in some cases, the same part number). MSD raised the bar even higher with the revised Digital 6AL Ignition Control!
The wiring of the Digital 6AL is routed out one end of the unit through a sealed and locking connector. This eases installation and keeps your wiring looking neat and clean. The rev limiter of the 6AL is located right on top of the housing for easy access to the 2 rotary dials to set the limit in 100 RPM increments.
Inside the Digital 6AL you will find a microprocessor that monitors and controls every firing & rev limit. The circuits are updated with efficient components that help the ignition produce more power while drawing less current! In fact, the Digital 6AL delivers over 530 volts to the coil with up to 135mJ of spark energy for every firing! Increased output combined with MSD proven multiple spark series is a win-win situation!
The Digital 6AL is supplied with the wiring harness and the components needed for installation. The 6AL is also supplied with vibration mounts. Both ignitions are compatible on 4, 6 or 8-cylinder engines with 12-volt, negative ground electrical systems. They will accept trigger inputs from breaker points, amplifiers & magnetic pickups.
