Process West Intake Manifold Cable Throttle Reverse Orientation - Subaru WRX / STI (GC8) 1999-2000
The Process West Intake Manifold with cable throttle and reverse throttle body orientation suits the 1999-2000 GC8 Subaru WRX and WRX STI. It pairs a billet plenum and bell mouths with thick-wall polished CNC mandrel-bent tubing, TIG welded and rated for boosted use up to 100 psi. Plenum and runner lengths are tuned for low and mid-range torque, and Process West claims gains of 10% or more on a stock setup. Custom throttle flanges are available on request, and a Track version, recommended for builds without air conditioning, can be supplied with shorter billet TGVs.
