Description
The Process West billet intake manifold is the result of years of research, multiple prototypes and an uncompromising design process. It is the highest level of induction engineering available for the Subaru WRX and STI, where precision aesthetics and outright performance are equally important.
Billet construction throughout
A full billet plenum with generous billet bell mouths and thick-wall polished CNC mandrel-bent tube components, assembled with high-end TIG welding, suitable for boosted applications up to 100psi.
Reverse throttle body orientation
This configuration runs a reverse-orientation throttle body position, suited to intake and engine-bay setups where the standard orientation is not practical. The Bosch drive-by-wire 74mm throttle body gives precise control at all power levels. Custom throttle flanges are available on request.
Real performance gains and broad compatibility
The plenum volume and runner length are optimised for strong low and mid-range torque without sacrificing top end, with gains of 10% or more even on a stock setup. The range is modular, covering everything from the MY99 GC8 through to the latest WRX and STI.
