MSD 6AL Ignition Box with Rev Limiter for use with a Distributor.

Whether you have a powerful street machine, hard working truck or trick street rod, the powerful multiple sparks of the MSD 6AL will ensure complete combustion. Benefits such as quicker ETs, easier starting, reduced plug fouling, more power and even increased fuel economy can be expected with the 6AL's high energy multiple sparks. Like all of the MSD 6 Series Ignitions, the 6AL will work with virtually any vehicle as long as it has a 12-18 volt electrical system.

The Digital 6AL has a microprocessor that monitors and controls every firing and rev limit. All wiring is routed through one end of the unit through a sealed and locking connector. The rev limiter is located on top of the housing for easy access to the two rotary dials to set the limit in 100 rpm increments. The wiring harness, vibration mounts, and components you'll need for installation are included.

We're here with MSD's digital 6AL ignition system. The Digital 6AL is going to fit your '64 through 1995 Mustang. It has a built-in micro control that's constantly analyzing your engine's inputs, so it can compensate for necessary high RPM changes. MSD stands for "multiple spark discharge" meaning each plug is getting multiple sparks at lower RPM. At a higher RPM, it provides one large spark for maximum burn, maximum efficiency, and maximum power. Unlike the factory system, the MSD has a capacitive discharge design. This basically means it has a capacitor stored inside and provides maximum voltage to the coil even at high RPM.

The 6AL also has a soft-touch rev limiter which is going to drop spark to individual cylinders within one percent of the desired RPM. The MSD digital 6AL comes with everything necessary for installation. It comes with a harness to tie into a MSD distributor, separate harness if you're tying into your factory ignition system, and all the necessary hardware as well. The MSD digital 6AL is an excellent choice if you're looking for more performance from the ignition of your '64 through 1995 Mustang.
