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). For 2011, the bar has been raised even higher as we introduce the all new Digital 6AL Ignition Control! 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. The rev limiter was moved right on top of the housing for easy access to the two rotary dials to set the limit in 100 rpm increments. 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! In fact, the new Digital 6AL delivers 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!

Autotronic Controls Corp. (ACC) was founded in 1970 as a research and development company by two engineers from White Sands (New Mexico) Missile Range. The men and their other partners were working on a lean burn fuel system called the Electrasonic Fuel Induction system to help fuel economy of new and older automobiles. As the new fuel system was being perfected, the air/fuel mixture was becoming so lean that it was difficult for conventional breaker points and early electronic ignitions to ignite it. The men of ACC then started investigating a new ignition system by using modern technology called capacitive discharge (CD). The CD design opened another door for the ignition, the capability to spark multiple times. ACC has produced the best performing and most popular performance ignitions for over 20 years. The high energy spark of the CD design combined with multiple sparks resulted in a potent ignition. Not only did the multiple spark discharge (MSD) ignite the lean fuel mixture, it made overall improvements in the engine's performance! Improved starting, smooth idle, less emissions and more power are benefits every car and truck can take advantage of, especially race cars. Professional racers learned of the new MSD quickly and soon word spread throughout the racing world. Since then, MSD Ignition Controls have gone on to be the ignition of choice of the top professional drivers in NHRA, IHRA, NASCAR, World of Outlaws, DIRT, SCORE, IDBA and many more. Together, our team designs, develops, tests and manufactures the entire line of MSD products including Ignition Controls, Coils, Timing Accessories and Spark Plug Wires and Accessories. MSD, housed in three buildings includes four engine dynos, two chassis dynos, complete CNC and machining centers, modern shipping and packaging areas plus assembly and burn-in departments.
