Digital 6AL Ignition Box - Part #6425
MSD started with a clean slate and drew up plans for an all new housing. They kept the same footprint as the traditional 6AL but lowered the profile for a sleek look. The wiring is all routed out one end of the unit through a sealed and locking connector. This eases installation and keeps your wiring looking neat and clean. The rev limiter was moved right on top of the housing for easy access to the two rotary dials to set the limit in 100 rpm increments.
Inside the Digital 6AL you’ll find a microprocessor that monitors and controls every firing and rev limit. The circuits are updated with efficient components that help the ignition produce more power while drawing less current! In fact, the new Digital 6AL delivers over 530 volts to the coil with up to 135mJ of spark energy for every firing! Increased output combined with MSD’s proven multiple spark series is a win-win situation!
The new Digital 6AL are supplied with the wiring harness and the components you’ll need for installation. The 6AL is also supplied with vibration mounts. Both ignitions are compatible on 4, 6 or 8-cylinder engines with 12-volt, negative ground electrical systems. They’ll accept trigger inputs from breaker points, amplifiers and magnetic pickups.
Pro-Billet Distributor - Part #85551
This is MSD's most popular performance distributor! The housing is machined from a billet of 6061-T6 aluminum on a state-of-the-art CNC machine producing exact tolerances. For high rpm stability, a .500” steel shaft is supported by a sealed ball bearing and a long sintered bushing. This shaft also receives a QPQ coating for friction reduction and resistance to corrosion. A precision machined reluctor is attached to the shaft which triggers the magnetic pick-up mounted in the housing. This high output magnetic pick-up is the most accurate way to trigger your ignition. Plus, with no moving parts to wear or adjust, the pick-up is maintenance free! Just above the pick-up is MSD’s adjustable mechanical advance assembly. Different springs and stop bushings are supplied so you can tune an advance curve to match your application.
8.5mm Super Conductor Wire Set - Part #35379
The MSD 8.5mm Super Conductor Wire is "the" performance wire. Engineered from the inside out, the 8.5 offers everything you have ever wanted in a wire; incredibly low resistance without electronic interference! In a single 12" length of Super Conductor Wire there is only 40 - 50 ohms of resistance! That is the lowest resistance of any helically wound wire. To accomplish this, MSD uses a copper alloy conductor due to it's great voltage carrying capabilities. The low resistance results in less loss in spark energy so more reaches the spark plug. The conductor is wound extremely tight around a special center core. So tight in fact, that there is over 40 feet of conductor wrapped into a single foot of plug wire. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective Electro Magnetic Interference (EMI) "choke". This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle. The outer sleeve that surrounds the conductor assembly is just as impressive. A proprietary blend of silicone and synthetic material produce a sleeve that is highly resistant to high heat as well as abrasion and tears. These wires have a multi-angle boot end at the spark plug. A coil wire is included as well.
We can also supply you with a universal set where you cut and make the wire lengths yourself. If you need this set instead (part #31199), please let us know in the notes section when buying. These wires will come with straight ends at the spark plug.
Blaster SS Performance Ignition Coil - Part #8207
Don’t let the compact size of the Blaster SS Coil fool you, because it is packed with performance! The efficient E-core windings are designed to produce high amounts of current without sacrificing the voltage output. In fact, when used with an MSD 6 Series Ignition, the Blaster SS produces 300 milliamps with a maximum voltage output of 40,000 volts!The secondary windings are wound on a segmented bobbin which reduces the chance of voltage breakdown between the primary and secondary windings. For more protection, these windings are encased in a polyurethane compound for complete protection against vibration. The Blaster SS features brass terminals and a sturdy Rynite housing. It is supplied with a 90° boot, terminal and vibration mounts. A great addition to CD Ignitions and some stock applications.
