## Overview

The MSD 6425 Digital 6AL Ignition Control is a high-performance ignition box designed for 4, 6, and 8-cylinder engines. Featuring a microprocessor-controlled rev limiter adjustable in 100 rpm increments, it delivers over 530 volts and 135mJ of spark energy per firing. Its sealed, locking wiring connector ensures a clean installation, while built-in LED diagnostics provide real-time system status. Engineered for efficiency, it produces more power with less current draw, making it a top choice for enthusiasts seeking reliable, tunable ignition performance.

## Description

Built-In Adjustable Rev-Limit Control. Inside the Digital 6AL, you'll find a microprocessor that monitors and controls every firing and rev limit. The circuits are updated with efficient components that help the ignition produce more power while drawing less current. The Digital 6AL delivers over 530 volts to the coil with up to 135mJ of spark energy for every firing. This increased output combined with MSD's proven multiple spark series is a win-win situation. The Digital 6AL is supplied with the wiring harness and the components you'll need for installation. The 6AL is also supplied with vibration mounts. Both ignitions are compatible on 4, 6, or 8-cylinder engines with 12-volt, negative ground electrical systems. They'll accept trigger inputs from breaker points, amplifiers, and magnetic pickups. The MSD 6AL Ignition Control set the standards that other ignitions strive to reach. In fact, you'll 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 two rotary dials to set the limit in 100 rpm increments.. CARB EO: D-40-43

Review: I installed this on an older 95 LT1 v8 it really helped give it a boost in spark and car runs well. Note this was not a stock engine. It has a large cam, ported heads and Headers. Another note. I also have the MSD coil but still use the stock opti spark distributer. one thing that makes a big difference is using the correct oil seal on the distributer once I finally installed the proper oil seal that looks like a standard oil seal all the problems with the opti spark went away after cleaning the oil out of the inside. Don't need to waste money on a 595.00 MSD distributer. Iv'e only heard bad reviews about them. this opti spark distributer was only 45.99
Review: Muy buen producto recupera entre 10 y 15 caballos, las conexiones simples y de muy buena calidad vale la pena la inversión para actualizar el encendido de un clasico
