Product images may differ from actual product appearance.

MSD's HEAT HEI Module is a direct plug-in for the 4-pin HEI module and will produce up to 7.5 amps of current. This increased energy will continue through racing rpm reaching 9,000 rpm!
The Digital Module is extremely accurate in its delivery of energy resulting in more accurate ignition timing. Another unique feature is an adjustable rev limiter. You can dial in an engine saving rev limit ranging from 5,000-10,000 rpm. To get the most performance out of the Digital HEI Module, MSD offers a performance Coil as well.
