MSD 7AL-3 ignition boxes have been a favorite of sportsmen and racers that want adjustments at their fingertips. For nitrous fans, there are four separate stages that can be activated independently yet add up together. Plus there's an RPM Activated Switch for precise control over a circuit. These 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
