Fitment Disclaimer
Note: The manufacturer officially specifies these injectors (3C3Z-9E527-ECRM) for use in 2003 and early 2004 Ford 6.0L Powerstroke diesel engines.
However, based on industry experience and interchangeability within the 6.0L platform, these injectors can also be used in later 2004–2007 model year engines which calls for 4C3Z-9E527-ARM. While they will physically fit and function, they may not reflect the exact OE revision originally equipped in later production trucks.
