Not sure which part you need?
Confirm all four of the following before selecting a replacement injector.
Exact engine model
Confirm the full engine model designation from your data plate — for example, 502 Magnum MPI or 502 MAG MPI.
Engine serial number
Locate the serial number on your engine data plate. Serial ranges are the most reliable way to confirm which injector was factory-fitted to your specific engine.
Existing OEM or injector number
If you have the OEM part number from the original injector or a service manual, this is the most direct identification method. Cross-reference it against the table below.
Physical injector characteristics
Connector type, body length, O-ring configuration and any visible markings or colour bands can help confirm the injector family. Use physical characteristics together with OEM/serial verification, not as the sole method.
