MSD 6631 Ignition Control Module

For use in Circle Track and Professional Racing, with Fast Rev Limiter;

Professional race teams have been relying on the power and endurance of our 6 HVC Ignition Control. The advanced component design and circuitry of the 6 HVC Ignitions produce incredible voltage with high current output. Internally there is an efficient heat sync, solid component mounting and it's all encased in a clear epoxy. The rpm limit is adjustable with plug-in modules and the wiring is routed into NASCAR approved Deutsch style MSD connectors.

The Fast Rev limiter is very quick and accurate compared to our Soft Touch Rev limiter.;
