Alliant AP65122N (No Core) Fuel Injection Control Module (FICM) 2003 Powerstroke RP27510 computational fluid dynamics were usedThe 6. 0L Powerstroke relies heavily on consistent voltage out of the fuel injection control module to properly fire the injectors. The original FICM frequently fails and or delivers less than adequate voltage, causing hard starts, rough idle, poor fuel economy, and overall less than satisfactory performance. If your FICM is in need of replacement, check out this quality remanufactured unit from Alliant. Cross Reference Part Numbers: 4C3Z12B599ABRM
