Remanufactured C7 Injectors

Remanufactured C7 Injectors

Program Highlights

Delphi Technologies continues to bring added value to your business by extending our all makes product offerings with new Caterpillar® (CAT) engine applications. The CAT C7 engine series is one of the most popular engine platforms in the market today.

Unit Injectors are our core expertise. Delphi brings more than 25 years of EUI design experience, which is why we are the world’s leading EUI supplier. Delphi utilizes its OE engineering capabilities to ensure that each injector is remanufactured with a unique trim code to deliver the quality that you have come to expect from Delphi. Delphi uses the same OE expertise and stringent standards for remanufactured parts as it does for its OE applications. In our reman facility, all injectors are fully disassembled. Each component is then thoroughly cleaned and inspected and all nozzles are new, matched and flowed. Units are then reassembled, tested on specialized test equipment for correct fuel, timing and pressure.

Delphi remanufactured C7 injectors include a new, unique trim code specifically engineered to ensure accurate fuel delivery, while maintaining power and efficiency. Visit for more information. 

Delphi remanufactured parts are produced in an ISO 9001:2008 and ISO 14001:2014 certified facility.

HTK111 Injector Seal Kit

Delphi offers high-quality seal kits for Remanufactured C7 Injectors. These seal kits are crucial for injector performance.  


Did you know? 

To ensure proper engine performance, the new unique trim code provided must be entered into the ECM. 

The trim code eliminates any variation in injector performance due to small differences in manufacturing tolerances, friction between components and fuel flow.
