VB FA24 WRX Intake Manifold

The Process West intake manifold is purpose-engineered for the Subaru WRX VB FA24 engine platform. This intake manifold replaces the factory unit to deliver improved airflow characteristics and enhanced throttle response across the rev range. Precision-designed runners and plenum geometry work to optimise air distribution to each cylinder, supporting both stock and modified tuning applications. Built from quality materials with a focus on Australian conditions, this manifold suits workshops targeting consistent performance gains and reliable operation on the VB chassis.
