Holley EFI Hall Effect Crank Trigger Sensor HSXSM11PA this dual-plane intake is designedP N 554 118 is designed as a drop in sensor replacement for flying magnet crank trigger setups using a 3 4 16" threaded magnetic sensor. This sensor is a Hall Effect sensor, meaning it outputs a square wave signal, which is ideal for use with most Electronic Fuel Injection Systems. This sensor is to only be used with a trigger wheel with "flying magnets". It does not detect a ferrous steel target. Holley is quickly becoming The New Standard In EFI!
