Fitment: Suits GU Patrol ZD30 common rail models built from August 2004 onwards. Direct replacement housing with 30% more airflow, allowing increased boost 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 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.

Pre-Order Information
Items where the “Add to Cart” button is replaced with “Pre-Order” are classified as pre-order items. When placing a pre-order, a warning box will appear outlining the terms and conditions, including the estimated delivery timeframe.
Please keep the following in mind:
Stock is not on hand – we have no control over delivery times until the stock arrives.
Patience is required – pre-ordering secures your item, but fulfilment depends on supplier availability.
High-demand items – pre-orders are the best way to lock in popular products, which often sell out before they even land.
Allow a buffer – please add 2–3 weeks to the provided ETA to account for any unforeseen delays beyond our control.
Pre-ordering ensures you don’t miss out on in-demand products, and we’ll keep you updated as soon as your order is ready to ship.
