The all new 7AL-3 is Better in Black
The MSD 7AL-3 Ignition Control has been a favorite of sportsman racers as well as racers that run multi-stage nitrous systems. The ignition combines 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 RPM Activated Switch.
For 2013, MSD is relaunching the 7AL-3 with upgraded features, a new look and updated internal components including surface mount circuitry. The new ignition, PN 7330, is easy to spot with a black anodized housing and features 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.
The updated 7AL-3 will begin shipping at the beginning of February 2013. The new part number, PN 7330, will replace the PN 7230 which will be obsolete by the end of January. All orders for the original PN 7230 will be replaced with the PN 7330.
Looks can be deceiving. Sure the upgraded 7AL-3 Ignition Control looks like its red counterpart, but there are plenty of changes internally to improve efficiency with surface mount assembly technology as well as refined user controls.
