The MSD 6AL ignition control box is the centerpiece of our ignition system. This is the newest version of the 6AL, which delivers 530 volts as well as 135 mJ of spark energy to the coil, resulting in full combustion every time the coil fires. If you’re familiar with the old 6AL ignition box, you’ll notice that this newest version has a lower profile yet still shares the same footprint as the old-generation 6AL. By far the biggest difference is that the 6AL is no longer analog—it’s now fully digital!
