MSD 6421 Digital 6AL-2 Ignition Control

Product Description
$419.95
Maximum quantity available reached.

This MSD 6421 Digital 6AL-2 is the standard of the Ignition Control industry! This unit delivers over 535 volts to the coil with up to 135mJ of spark energy for every firing! Coupled with a sleek low profile, all wiring is routed out one end of the unit through a sealed and locking connector for a clean installation.

MSD relocated the rev limiter to the top of the housing for easy access to the four rotary dials that set the limit in 100 rpm increments. Inside the Digital 6AL-2, a microprocessor monitors and controls every firing and rev limit while pulling less current. Increased output combined with MSD's proven multiple spark series is a win-win situation!

This ignition is compatible on 4-, 6-, as well as 8-cylinder engines with 12-volt, negative ground electrical systems. It will accept trigger inputs from breaker points, amplifiers, as well as magnetic pickups.

Wiring harness, vibration mounts as well as all components needed for installation are included.
