This replacement cap and rotor set fits FAST XDi Dual-Sync distributor assemblies, restoring the discrete switching and signal integrity those units provide. Intended as a service item for Dual-Sync installations, the kit matches the distributor's factory-aligned reluctor and pick-up layout so you can maintain precise ignition timing and reliable operation with aftermarket FAST ignition systems.
