MSD started with a clean slate and drew up plans for an all-new housing. We kept the same footprint as the traditional 6AL but lowered the profile for a sleek look. The wiring is all routed out one end of the unit through a sealed and locking connector. This eases installation and keeps your wiring looking neat and clean.Inside the Digital 6A you'll find a microprocessor that monitors and controls every firing. The circuits are updated with efficient components that help the ignition produce more power while drawing less current! In fact, the new Digital 6A deliver over 530 volts to the coil with up to 135mJ of spark energy for every firing! Increased output combined with MSD's proven multiple spark series is a win-win situation!
The new Digital 6A is supplied with the wiring harness and the components you'll need for installation. Compatible on 4, 6, or 8-cylinder engines with 12-volt negative ground electrical systems. Accepts trigger inputs from breaker points, amplifiers, and magnetic pickups.
