Heya Guys...

Quick one really, is there any difference in the colour codes on the z32 air flow meters?

I've got one coming over from japan which is orange label...and the one i've got already is yellow...

I know for a fact that the yellow one is off a z32,i removed it from the car...

So what is the difference if any?

Many thanks in advance.

Hi guys,

Green label AFM = R33 Series 1 RB25

Pink label AFM = R33 Series 2 RB25 <---- You are here :D

Orange label AFM = 300zx Twin Turbo (Z32)

Yellow Label AFM = Q45 Infiniti V8


You'll probably find that the 300zx you got the AFM from had been upgraded to the Q45 AFM

Also the Q45 is 90mm where all the others are 80mm

Hope this helps

Doesnt the Q45 max out before the z32? (thinking of another thread I saw on here before)
I don't think its a case of maxing out, I seem to recall the Z32 has more resolution (for tuning) where the Q45 can flow very slightly more but is less tunable. This means they can cope with similar power depending on your ECU map.

The Q45 looks better with its 90mm diameter though :D

Apparently the standard ecu will not recognise it, so generally you will need to either remap or get a different ecu...

Please correct me if i'm wrong....But this seems to be the general gist on the forum.

Hope it helps.
