D8738

The MSD 6T, 6TN and 6ALN were designed with severe duty racing applications in mind. These ignitions share the same output and circuits of the other 6A Series, but have a few special features of their own. The 6T and 6TN are equipped with a special 4-wire connector to plug into an external rev limiter, This rev limiter is designed exclusively for the MSD 6T, 6TN and 6-HVC Ignition Controls. It has a special 4-wire connector that plugs into the MSD Ignition. The Soft Touch is a very smooth rev limiting action that "holds" the engine at the selected rpm limit without backfires, extreme roughness or engine damage. The rpm limit is adjusted with plug-in modules and 6,000, 7,000 and 8,000 modules are supplied.
