One set has the following info:
2C5E-A4A
9F593 242
They are EV6 style with USCAR connectors, have purple tips, two hole nozzles and came with my 05 Aviator motor. From what I've gathered, they appear to be 24lb injectors and supposedly also came with 03 Marauders as well as the Aviator, but I haven't been able to determine any of the pertinent tuning info.
The other set has the following info:
YF1E-F4B
9F593 161
They also are EV6 style injectors with USCAR connectors. They have four hole nozzles, maroon tips and came with the 02 Explorer motor that's currently in my car.
If I can find the specs, I'd like to see if the YF1E's would support the power my 2V motor is making (probably somewhere in the ballpark of the Mustang's 260HP). Supposedly, the EV6 injectors are better at atomizing the fuel. Sicne I have the injectors, it couldn't hurt to try them
