MSD 6420 6-AL Multiple Spark Ignition Box w/Rev Limiter

MSD 6420 Universal MSD 6AL Mutiple Spark Discharge Unit w/ Rev Limiter

MSD 6AL ignitions are the perfect choice for the street or the track

The powerful capacitive discharge, multiple sparks ensure complete combustion of the air/fuel mixture to increase power and performance

MSD has taken the proven performance of the 6A and added a rev limiter

The soft touch rev control will protect your engine from overrevving

Adjustments are easily made with plug-in modules, so there are no dials, switches, or programs to deal with

At your selected rpm, the soft touch begins dropping the spark to some of the cylinders, and on the next cycle, these same cylinders are fired to prevent loading up with fuel. The result is a smooth and accurate limiting action without backfires or roughness

Works with virtually any 4, 6, or 8-cylinder vehicle with a distributor, as long as it has a 12-18 V electrical system

Includes rubber shock mounts and modules for 3,000, 6,000, 7,000, and 8,000 rpm

Simple installation on 1964 ½ thru 1995 Mustang and many other vehicles

Factory tach may not work on some pre-1986 Mustangs, MSD tach adapters are available

Great for Street, Strip and Road Racing applications
