Z32 aif flow meter (with plug)
With repect to uprating the stock air flow meter which will max out well before 400bhp there
are two options that I'm aware of, the Z32 (80mm diameter) and the Q45 (90mm diameter). As I could get hold
of a second hand Z32 for a good price with a wiring plug from a reliable source I opted to go down this route.
For those that do not know, the Z32 AFM comes out of the Nissan 300ZX.
