Process West Intake Manifold Street Version Black Subaru WRX 2002-2005

Part #: PRW - PWIM004B. The Process West Street Version Intake Manifold is a masterpiece. Years of real - world research, testing, and multiple prototypes and redesigns have led to this great product. It features a billet plenum and CNC - machined tubes with high - end TIG welding, able to handle 100 PSI of pressure in forced induction setups. The plenum is made from strong billet aluminum, with thick - wall polished CNC mandrel - bent tube components.
