## Description

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.

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.

Review: amazing so far no issues - bought this along with the distributor after my petronix system gave out this thing is amazing no issues fires up every time! i recommend routing it somewhere that has good cold air flow get a little warm
Review: I was on the fence. - Been rebuilding a 1999 Chevy Silverado 1500 4.3 Vortec. The truck is rust free and it has a been a learning curve working on computer driven engine. My background, 1960, 70, 80 and some 90 vehicles. Back in the eighties my boss started using MSDs. I never, it being electrical and all, got into MSDs and the need for them not understanding what their function was. Fast forward, the issue this truck was having was cold start. I needed to crank it over quite a bit, not happy, to get it to turn over. In my research to find a cure, yes scan tool in hand, started with a new coil. I went with MSD coil and in their installation instructions it went over on how to also install their MSD box. With the added wire loom, a bit costly for what you get, it was plug and play. Your ICM, ignition control module, you don’t touch. This is nice, for if ever the MSD acts up, just plug it back as it was. It made a believer out of me when with ten-degree weather on the first crank it came to life. So yes, it solved my issue, and I would recommend it.
