The Holley Crankshaft Sensor with Ferrous Metal Target (part number 554-124) is a precision ignition trigger component engineered for high-performance EFI systems. This 12mm x 1.00 threaded sensor integrates with Holley EFI engine management kits to deliver accurate crankshaft position data, enabling precise fuel and spark timing control. The ferrous metal target design provides reliable magnetic sensing in demanding engine environments where consistent signal strength and minimal electromagnetic interference are critical to engine stability and performance.
Designed for compatibility with Holley EFI system configurations, this crank trigger sensor operates by detecting ferrous reluctor rings or targets on the crankshaft. The 12mm threaded mount allows secure installation in standard engine block locations. The ferrous material composition ensures strong magnetic coupling with the sensor's pickup coil, producing the clean digital signal required for modern EFI controllers to manage combustion timing with precision. Accurate crankshaft sensing is foundational to proper idle quality, transient response, and overall engine efficiency in fuel-injected performance applications.
This sensor serves builders and technicians installing or upgrading Holley EFI systems on carbureted or older fuel-injected engines. It is particularly suited for custom engine builds, restorations, and performance modifications where OEM ignition sensors are unavailable or incompatible. Proper crankshaft signal integrity is essential in supercharged and turbocharged applications where timing accuracy directly impacts boost control stability and knock detection function.
Holley EFI sensors are recognized in the performance aftermarket for integration reliability and signal consistency across a wide range of engine displacements and configurations. The Crankshaft Sensor with Ferrous Metal Target is a direct OEM-equivalent component and should be installed according to Holley's system documentation to ensure proper gap distance and sensor alignment with the reluctor target.
