FAST Ignition Module, XR-I, Chevy V8, 1957-74

Tired of setting your points, or hitting that magical point at higher RPM where they seem to float, costing you power and performance? It?s time to pull out those ancient contacts and benefit from modern day, digital technology with the FAST XR-i Replacement Module. The XR-i is a compact module that bolts directly in place of the breaker point assembly. It simply triggers from the factory cam lobe, making installation a breeze with only two wires to connect. The microcontroller of the module manages the signal and dwell time in the coil to produce a much higher output spark that will improve the performance and driveability of your classic as well. Another great feature is a built-in rev limiter to protect your engine in the event of driveline failure or a missed shift.
