Question S4 NA injectors riddle me this question

Two injectors, both Denso, both part number 19550-1350.

But one has a centered lower guide and one has an offset guide.

I'm 99% sure the offset one is high impedance 460cc.

Since same part number the other so has to also be 460cc. But doesn the center guide indicate that it's low impedance? It's been so long since I worked on a S4 NA, I simply don't remember for sure.

Am I right?
