HPD Nissan Patrol GU 2000 - 2004 ZD30DI Airflow Meter Housing

The HPD Airflow Meter Housing allows you to tune your engine to run the correct air-fuel ratio (most of the ZD30 DI 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 Airflor Meter.

The only difference between the 2000 - August 2004 (Series 1-3) and August 2004 onwards (Series 4) Airflow meter housing is that the first has a round sensor and the second has a rectangular sensor.
