Message Original post here. The injectors appeared to be new and mine ohmed out perfect just like the set blueridge got. They also are definitely 550cc injectors since the AFR is right after reprogramming my ECU.

The problems I had were that 3 of the six were stuck closed. After reading about new injectors on the Witchhunter site it appears this can be a common problem with new injectors that have had a long shelf life. I did manage to get the three working and they are doing fine now I just didn't catch the problem before installation. I recommend that anyone buying these injectors click test them with a 9 volt battery. If they don't click they are stuck which can usually be fixed by lightly tapping on the injector body.

The other problem was since these are Subaru injectors the tabs on the wiring connectors are different. These injectors come with new pigtails so it was just a matter of swapping them out.

For the money I am definitely happy with them just wish I had tested them better before installation.
