Crank Sensor HE Flying Magnet

The Crank Sensor HE Flying Magnet by Holley is an essential component for builders and enthusiasts seeking reliable engine timing control in high-performance and modified applications. This sensor is crucial for any EFI-equipped engine, converting crankshaft rotation into precise electrical signals that the engine control unit uses to manage ignition timing and fuel injection.

The innovative flying magnet design features a rotating magnet target mounted on the crankshaft or harmonic balancer, paired with a stationary magnetic pickup coil. As the magnet rotates past the coil, it generates alternating voltage pulses that the ECU interprets as crankshaft position and speed. This design enhances reliability by eliminating the wear and maintenance issues associated with traditional mechanical sensors.

Ideal for tuning street engines, building weekend warriors, or restoring classic vehicles with modern ignition systems, this crank sensor ensures consistent performance and drivability. Its compact dimensions allow for flexible mounting in tight engine bays, while its precision construction guarantees minimal runout tolerance and reliable signal quality.
