PN 8278 is the replacement Hall Effect Sensor for flying magnet crank trigger setups using a 3/4-16" threaded. 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.


  • Most accurate way to trigger your electronic fuel injection (EFI)
  • 3-Wire Hall Effect sensor that is less susceptible to noise interference
