Does anyone know what is different between the F1ZZ-9F593-C and the F0TZ-9F593B fuel injectors? The vehicle in question is a 96 F250 with a 5.8 L.

Thanks,

 

There was a design change with the Bosch injectors, but I'm not sure what time. Are both of those numbers the same flow rating?

 

I think so? They are OEM numbers for the 5.8L. P/N search shows either P/N for my '91, but only shows the F0TZ-9F593B for my '96. I was curious if I would encounter problems using the F1ZZ-9F593-C with my '96 wire harness and computer.

 

I'm not really sure what the difference would be. I'd almost think that the newer part might have a little better spray pattern, but it probably doesn't make much difference which one you go with, so long as the flow rate is the same.
