Emissions application limits

CARB Executive Order D-40-43. For compatible 1995 and older vehicles without OBD II. The exemption applies only when the exact part, vehicle and installation meet the order and manufacturer instructions. Mechanical compatibility alone does not establish emissions eligibility; later vehicles and other configurations are not covered by this statement.

Manufacturer specifications and installation guidance

Inside the Digital 6AL, you'll find a microprocessor that monitors and controls every firing and rev limit. The circuits are updated with efficient components that help the ignition produce more power while drawing less current. The Digital 6AL delivers over 530 volts to the coil with up to 135mJ of spark energy for every firing. This increased output combined with MSD's proven multiple spark series is a win-win situation. The Digital 6AL is supplied with the wiring harness and the components you'll need 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'll accept trigger inputs from breaker points, amplifiers, and magnetic pickups. The MSD 6AL Ignition Control set the standards that other ignitions strive to reach. In fact, you'll 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 two rotary dials to set the limit in 100 rpm increments.
