DESCRIPTION Engineered for serious performance, the Process West Intake Manifold for the 2022+ WRX is the first and only of its kind for the FA24 platform. Designed using a hybrid construction of billet plenum, cast large-bore runners, and a fully functional billet Tumble Generator Valve (TGV) section, this manifold is built to deliver maximum intake flow while maintaining OEM functionality. After over a year of real-world testing on their in-house WRX, Process West brings a game-changing upgrade with precision fitment and dyno-proven results. WHY? This intake manifold is more than just an aesthetic upgrade. It’s a true power-adder. With increased plenum volume, optimized runner geometry, and precision internal porting, your FA24 engine will breathe more efficiently than ever before. Gains are substantial even on mildly modified WRXs, but the real magic happens on tuned setups, where airflow demands are highest. With a simple swap and retune, Process West saw power gains of over 40whp on their test car. If you're chasing more horsepower without compromise, this is the intake manifold you've been waiting for. FEATURES: CNC-machined billet plenum and TGV section Cast large-bore runners for maximum airflow Designed specifically for the FA24 in the 2022+ WRX Dyno-proven performance with gains up to 40whp Seamless fitment with OEM and Process West components COMPATIBILITY 2022+ WRX
