I have seen a R32 GT-R for sale in Japan with Z32 airflow X 2 in the add.
any advantage in having these?

Yes... Don't understand fully why, but they are larger diameter and where the standard ones often max out around 550bhp the Z32 ones are good for much much more!

The Z32 AFM's have a higher resolution and more dynamic range than the stock GTR items.

What this means is that they can more accurately determine the difference between two air flows (resolution) and they can usefully measure less / more airflow (dynamic range).

In the real world this is good because when your engine is being tuned to suit the Z32 AFM's, you can adjust the fueling with a lot more accuracy across the rev range.
