Billet Airflow Meter Housing - Nissan Patrol GU4 Series 4 ZD30Di & ZD30Cr

The HPD Airflow Meter Housing is a direct replacement upgrade and has been designed to allow 30% more airflow so you can increase boost pressure without affecting the ECU signal.
The HPD Airflow Meter Housing allows you to tune your engine to run the correct air-fuel ratio (most of the ZD30DI Patrols are running a rich mixture,) especially when fitted with a performance chip or module. Fitting the HPD Airflow Meter Housing will give your Nissan Patrol GU ZD30 increased performance and better fuel economy.

There are immediate benefits with this product scaling up to massive benefits if your ZD30 is highly modified. HPD is the only manufacturer we are aware of that are doing an engineered Airflow Meter upgrade for ZD30, which breaks through the limitations of the factory Airflow Meter.
