MSD’s popular 6AL ignition box has been completely redesigned and is now available in two powerful options: ULTRA 6AL and ULTRA 6AL PLUS! Don’t let the small size fool you! They both deliver a powerful spark of 135 to 150 millijoules every time it fires, from idle to redline RPM. This means you'll get quicker throttle response and improved starting. Both the Ultra 6AL and Ultra 6AL Plus are laden with features that make it better than the Ultra 6A. These features include built-in start retard, 3 rev limiters, step retard, and an all-new MSD mobile app for configuring your ignition. The MSD app makes it easy to set up your MSD Ultra 6AL ignitions. You can set up cylinder selection, step retard values, launch, burnout, and max RPM values all from your touchscreen. Start retard and step retard values can also be adjusted through the MSD app.
