    Rated 5 out of 5 by from 5 stars sort of Well I did not expect to have to change out my MSD box and so changing two boxes-“I had a spare”. Apparently the MSD Blaster coil was the culprit. I did a Ohmmeter test on the coil and it was in spec I checked the entire harness on my drag car for a short. After frying my spare MSD box I was frustrated. Talking with MSD Tec they revealed that although the coil checked to specs when powered it can short . I bought a new coil and a MSD box Problem solved. I got a repair authorization number from MSD to repair the burnt boxes Hopefully MSD will be kind on the repair cost.

    Rated 5 out of 5 by from Replacement Bought this unit to replace an older Digital 6 unit that was not serviceable. This unit also all the features that I needed and was a little cheaper that a new Digital 6. This unit is a little smaller that my older unit.

    Rated 5 out of 5 by from Fantastic ignition I've had this box installed for a month now and performance is far above what my old duraspark was capable of. Fires up instantly, looks great, easy installation, and having a built in 2 step just seals the deal.

    Rated 5 out of 5 by from Excellent upgrade over the original AL 6 box. Smaller and the ignition indicator light is a real plus to signal proper ignition operation.

    Rated 5 out of 5 by from MSD with great features!! I purchased this about one month ago. I am so glad that I did because we use it in a stock car. It solved all my issues with my ignition. Easy install and easy to work with.
