Process West Billet Intake Manifold - Subaru WRX / STI (GC8) - Cable Throttle, Reverse Orientation
This Process West Billet Intake Manifold suits the MY99–00 GC8 WRX and STI with a cable throttle in the reverse orientation. It combines a full billet plenum and billet bell-mouths with thick-wall polished CNC mandrel-bent tubes, TIG welded and rated to 100 psi of boost. The plenum volume and runner length are tuned for strong low and mid-range torque without giving away top-end power, and Process West reports gains of 10% or more even on stock setups.
Available in a silver or black finish.
Note: Suits MY99–00 GC8 WRX and STI with a cable throttle. Custom throttle flanges are available on request. Installation by a professional is recommended.
