Brand New MSD Digital 6AL Ignition Control Box with Built-In Rev Limiter, 520-540 Volts, Compatible with 4,6 & 8 Cylinder Engines, Produced by Holley Performance Products (Part #6425)

The MSD 6AL Ignition Control set the standards that other ignitions strive to reach. In fact, you will find ignitions from other companies that carry the 6AL name (and in some cases, the same part number). MSD raised the bar even higher with the revised Digital 6AL Ignition Control!

The wiring of the Digital 6AL is routed out one end of the unit through a sealed and locking connector. This eases installation and keeps your wiring looking neat and clean. The rev limiter of the 6AL is located right on top of the housing for easy access to the 2 rotary dials to set the limit in 100 RPM increments.

This one is the best OE standard replacement for OE:LX203.

Ignition modules will respond to a weak signal from the crankshaft position sensor and begin energizing.

Ignition modules are durability tested for 500 thermal cycles ranging from -40C to +125C.

USB connection for ease of programming

Timing based on engine RPM and gear value

Advanced individual cylinder timing based on gear or time
