Growing up as a hot rodder and racer I remember buying my first aftermarket ignition parts and that giant yellow Accel coil hanging on the firewall of my Camaro looked cool and worked good. But I also wanted an MSD ignition box and I saved my money to get an MSD 6AL so that I had a rev limiter too and it was great. I still have that box on the car today! But boy have the MSD boxes come a long way since then. I have had several models and the new MSD Ultra 6AL and 6AL plus are the best out there with lots of features and technology you want in your street machine, hot rod, or race car. Check out all the information below.
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. Find out more about MSD’s latest products at holley.com
