MSD's 7AL-3 ignition boxes have been a favorite of sportsman racers, as well as racers that run multi-stage nitrous systems. Theses ignitions combine high-output spark energy for high-compression race engines, combined with the most popular drag racing accessories, including a 3-step rev limiter, 4-stage retards, a start retard, and an rpm-activated switch. MSD is re-launching the 7AL-3s with upgraded features, a new look, and updated internal components, including surface mount circuitry. The new 7AL-3s are easy to spot with a black anodized housing and a new adjustable start retard circuit. Racers will also be happy to learn that the ignition can now be used on 4, 6, or 8-cylinder engines!
Additional features include:
* Fits the same mounting footprint as the original 7AL-3
* Start retard is adjustable with plug-in retard modules
* Retard stages require positive 12 V to activate
* Surface mount assembly reduces internal components
