The Process West Intake Manifold for the 2022-on Subaru WRX (VB) with the FA24 engine combines a billet plenum, large-bore cast runners and a working billet TGV section, and was developed over more than a year of testing on Process West's own car. On their dyno it took the car from about 246 kW to about 275 kW at the wheels at the same boost target, roughly 12% more power and 10% more torque across most of the rev range, with gains said to grow at higher power levels. It needs a front mount intercooler because the throttle body sits lower and closer to the firewall, and many front mount kits, Process West's own included, also need the Process West throttle adaptor pipe (PWIM010AP). Choose the Standard Injection version, or the race-oriented Port Injection version that adds four port injector mounts.
