An updated ACDelco injector used in select newer GM port-injected, Flex Fuel, and CNG applications. Injector design and calibration may differ from PN 12613412.
Important: These two part numbers are not automatically interchangeable. Always verify the correct injector using the vehicle’s VIN, original injector number, connector, dimensions, fuel type, and required flow rate before ordering.
Why Choose Genuine OEM Injectors?
Offshore copies may look nearly identical, but their internal components, calibration, and quality control can vary. Lower-quality injectors may suffer from:
- Inconsistent flow between injectors
- Poor spray patterns or dead spots
- Inferior seals and internal filters
- Leakage or premature failure
- Potential engine damage from lean or rich cylinders
CPR Racing supplies genuine OEM components for consistent performance, dependable operation, and long-term reliability.
