What injectors do I have?

[Slowr/t]

I bought some factory nissian injectors from someone a year or so ago and just ran across them. I'm trying to figure out what kind they are. The numbers I have found on them are 1Z28 (or 6) AND 0G55. One injector has 0G60-6306. There is also A46-00 on three. Anyone know what they are? I have tried to put the numbers in google search but came up with nothing. Thanks in advance.

How about this, since they are unknown and are probably dirty, send them out to get cleaned and flow tested. Best way to figure out what they are flowing and you get the peace of mind knowing that they are good to go.
