Keith Browning Posted October 20, 2007 Share Posted October 20, 2007 We all remember the C94 injector deal in the early 2003 engines. They were replaced with the C95 injectors right? But that is a straight forward difference and I have been asked about using injectors from a 2006 truck in a 2003 engine. From my limited research, I asked my parts counter to see how many different injectors were available for the 6.0L. The answer: 2 - depending on a build date which coincides with the change from the 2003 engines and all engines since. So what is the actual difference between them? Is it physical? Operational? Are they interchangeable? I understand that the engines had some changes like camshafts and piston design that may have something to do with this. The only reference I can find is in the 2004 Update/Running Changes Coffee Table Book which says: Quote: DLC (Diamond Like Carbon) Coated Plunger The plunger has had a DLC coating applied to it. . The coating will further increase the robustness of the injector against poor fuel quality/water intrusion and will reduce the risk of internal scuffing. NOTE: This injector has different operating characteristics and cannot be interchanged with non-DLC injectors. Installing the incorrect injector could cause erratic or rough engine operation.
