The adapters will work on any other rail of that style. I had them on the N/A EJ22E rails I used to have. Those rails are long gone, however.
The injectors have maybe 50 miles on them. I put them in the day before I got T-boned in the old car. They have not been used since. The blemishes were there when I bought them from DeatschWerks. I asked them if they could go bigger, and they said yes, but they used cosmetically blemished units since they have to ruin a few to come up with a matching set. Didn't bother me. The one that looks bad still clicks into the plug. I can dig up my harness and take off the plug bodies to send with as well. The pins are the same, so no splicing is needed if you are handy with a sewing needle. Also, you may notice I replaced all the pan head screws with 8mm hex bolts/screws on the caps.
