While this distributor is designed primarily for use with sequential fuel injection systems that support Hall Effect crank and cam sensor inputs, they can also trigger TBI fuel injection systems. The precision-machined shutter wheel design ensures accurate timing, even at high engine speeds. If you have converted to a coil-per-cylinder ignition system, we offer a great looking blank distributor cap to save space and eliminate the unused cap and rotor.
