HPI Baja Airflow Roof Scoop BJ001 by GPM  [BJ001]

Low-profile roof scoop for HPI Baja

The BJ001 roof scoop is an alloy accessory designed for HPI Baja shells to manage air movement across the body and assist in cooling electronics. The alloy construction delivers a sturdy mounting surface with a compact silhouette aimed at off-road durability.

Fitting is usually direct on shells with common roof mounting setups: position the scoop over the existing holes or pads, fasten using suitable screws, and trim the body only where necessary to avoid contact with internal components. This scoop is primarily for aerodynamic and cooling purposes, not for adding structural strength.

For setup work, treat the scoop as a tuning tool. Small changes to its placement or tilt can shift airflow and change front/rear aerodynamic balance, which in turn can affect tyre loading and cooling flow to the motor or ESC. Check for clearance and rubbing after your initial track sessions and adjust as required.

As an aftermarket upgrade for HPI Baja buggies, this alloy roof scoop offers a robust option for airflow and cooling tweaks. Use incremental trimming and testing to confirm desired handling changes.
