Plazmaman BA/BF & Territory Forward Facing Inlet Plenum (BAFPLEN) - Ford Barra 4.0L
Upgrade airflow, performance potential, and engine bay appearance with the Plazmaman Forward Facing Inlet Plenum for BA/BF Falcon and compatible Territory Barra 4.0L applications. Developed for tough street and race use, this plenum has been proven on high-performance Barra combinations and is equally at home in a show-quality engine bay thanks to its clean fabrication and premium finish options.
At the core of the BAFPLEN design is Plazmaman's in-house developed spherical tapered plenum dome, engineered to promote positive turbulence and more even air distribution across all six cylinders. Six individual internal bell mouths feed the factory runners through a precision CNC-machined billet baseplate, helping support strong torque production and high-RPM horsepower. The plenum is constructed with a lightweight but rigid design and weighs approximately 3.5 kg.
Installation is designed to remain straightforward by bolting directly to the factory intake runners. The plenum also includes multiple vacuum ports for factory or aftermarket accessories such as boost controllers, MAP sensors, and blow-off valves. The factory fuel rail can be retained, or a Plazmaman billet fuel rail can be used. The factory throttle body mounts directly to the front of the plenum, with an optional extension wiring harness available separately for applications requiring additional throttle body wiring length.

Performance Design
The spherical tapered plenum dome and six individual bell mouths are designed to improve how incoming air is distributed to each cylinder. By promoting more consistent airflow across the engine, the plenum is well suited for high-output Barra combinations where balanced cylinder filling, torque production, and top-end horsepower are important.
