MSD 6AL Digital Ignition Control Box and Blaster HVC Coil

Control Box

The MSD Digital 6AL features a higher output with 530 primary volts and 135mJ of spark energy. Efficient components use less current to produce more power. Set an rpm limit on the MSD 6AL rev limiter with two rotary dials. Has the same bolt pattern as the original 6AL, but with a lower profile housing. Built-in LED for system checks. All wires exit the same side through a locked, sealed connector. Compatible with 4, 6 and 8-cylinder engines.
