Need identify injectors

[infinitedrift]

I bought these injectors from a member. He and I thought they were Subaru Sti 550cc but I really need to make sure for the tune. I have typed in the number on the side of injectors and can not find anything on them. I even called Denso and they could not find the injector with the numbers listed. They said sometimes thier aftermarket divsion is outsourced. When I look up the Sti injectors, they are the exaxt same color and size as mine but with diffrent part numbers...Can someone please help!

The injectors say:
Denso
7AMAW(ON ONE SIDE)
0580 721 27(THE OTHER SIDE SPACED OUT LIKE THIS)
IT ALSO HAS A LITTLE BAR CODE THAT TOO SMALL TO READ.

I have verifyed the flow rate and they came back as 535cc which everywhere I look says 535cc is usually advertised as 550cc. 1) My Enthaply tune is for 550cc will these work without issuses. 2) I was also told you can just adjust the fpr and safc to make'em run 550cc, is that true?

If you really want to be safe just have them flow tested.. Once you know what they put out it doesnt matter if they are out of a 2045 Ti-Fighter.... lol

A tuner does not really care, if he does its job properly he can guess the flow quite fast. As long as the injectors are big enough its ok.

dont mess with an FPR or an SAFC unless you know what you are doing (and have a wideband lambda sensor to check what it does)

The injectors were verified as 535cc and they can be tuned up to 550cc.. So were good.
