An all new design based around the MSD 6AL this latest digital 6A features a higher output (530v primary and 135mJ of spark energy) with less current draw. Installation is made easy with wiring being connected via a single sealed connector.Multiple spark improves combustion for improved power and drivabilityReduces engine emissionsImproves fuel economyWorks with points, amplifiers and magnetic pickup ignition systemsIncreases spark voltageBuilt in rev limiter which can be set in 100 Rpm incrementsWhether you have a race, rally or performance road car, the powerful multiple sparks of the digital MSD 6AL will ensure complete combustion. Benefits such as quicker times, easier starting, reduced plug fouling and more power can be expected with the digital 6AL's high energy multiple sparks.The Digital 6AL features a user settable rev limiter which can be set for revs up to 15,000 RPM at 100 RPM intervals. Works with virtually any vehicle 12-18 volt electrical system. Triggered using breaker
