RX7 air flow meter modified for NA6, everything needed to bolt directly into a NA6 miata. Testing has shown to give a +5 HP bump above 5-5.5k RPM as the stock AFM can't measure the airflow above those levels. I believe stock 1.6 AFM reads up to 250 CFM and the RX7 reads up to 300 CFM. Asking 40, I bought just the AFM for 50 already calibrated. Only thing I'd change would be to get a smaller pod filter.
