They are both 80MM.

RB25 series 1 AFM has green label and part no. 22680-02U00.
RB25 series 2 has a pink label, not sure of the part no.
Z32 has an orange label, part no 22680-30P00.

Pink - 22680-31U05
It's the one I have on my R34 GTT.
Is there anything to gain from using a z32 afm v. oem on a basicaly standard car?

so, simon, what have you heard is the actual max hp that the stock afm can handle. I've heard everything from 300-350hp.
I have an AX53B70-25 turbo on the way which at 0.8bar should give me around 320hp with my current setup. Do you think I should go with the z32 or just order a new rb25 afm sensor? after all the old one is probably starting to give.

Cheers!
Tomas

ER34GTT - I'd sell your RB25 AFM and buy a Z32 one as the RB25 will be running out of tuning capability by 320hp. The Z32 will let you carry on if you want upto 420hp (+/- 20hp)

I have a RB25 in my R32, running on a chipped ecu. But was tuned on a z32 maf. Right now I have a RB25 maf on it. What will be the down side if this ?
