MSD HVC PROFESSIONAL RACING IGNITION - MSD-6631

This ignition has a built-in rev limiter that will save the engine from over-rev damaged caused by spins, missed shifts or driver misfortune. This means there is no need to mount an external rev 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.

Must be used with HVC Coil PN 8250
