Rebuilt OEM GM 4.8L 5.3L 6.0L Fuel Injector Set

Restore your GM truck's power with a set of 8 rebuilt OEM GM Delphi 25317628 fuel injectors. These are the exact injectors originally used in 2001–2007 GM 4.8L, 5.3L, and 6.0L V8 engines. Each injector is professionally serviced, ultrasonically cleaned, fitted with new internal components, and flow-matched to OEM specifications using industry-leading ASNU equipment. The flow matching is within 2% to ensure maximum performance and a smooth idle. These injectors are designed for a direct fit on non-flex GM 4.8L, 5.3L, and 6.0L V8 engines manufactured between 1999 and 2007. They offer OEM reliability and are a plug-and-play replacement, meaning no additional tuning is required. The product comes with a lifetime warranty against failures or defects, providing peace of mind. Precision Auto Injectors rebuilds these injectors by starting with genuine OEM Delphi cores. Each injector undergoes rigorous testing for leak-down, dynamic flow rate, spray pattern analysis, and coil integrity. This process ensures that every injector meets or exceeds original OEM standards. The company emphasizes that these are not new injectors but professionally rebuilt OEM cores that perform to better-than-new standards. Vehicle compatibility includes a wide range of Buick, Cadillac, Chevrolet, GMC, Hummer, and Isuzu models with the specified V8 engines and year ranges, including specific trims like the Silverado 1500 HD and Yukon XL 2500.
