Process West Intake Manifold Cable Throttle Reverse Orientation - Subaru Impreza WRX/STI 1999-2000 GC# GF#

1999 - 2000 Subaru WRX, (GC/GF)
1999 - 2000 Subaru STI, (GC/GF)

When the standard throttle body position does not suit your build, the Process West Track Billet Intake Manifold in reverse orientation delivers the same uncompromising performance in a configuration that works for more demanding engine bay layouts.

Built for serious applications.

CNC machined from solid billet aluminium throughout, with generous bell-mouth runner entries, thick-wall polished mandrel bent tube components, and high-end TIG welding. Rated to 100psi of boost pressure and finished to a standard that no cast or fabricated manifold can match. This is a component built to perform at the highest level and look the part doing it.

Track-tuned performance.

The Track version plenum volume and runner length are optimised for aggressive torque delivery low and mid in the rev range, with strong top-end power to match. Gains of 10% or more have been recorded on completely stock setups, and customers regularly remove competing aftermarket manifolds to fit the Process West unit once they understand the difference in real-world performance.

This configuration is recommended for any performance build not requiring air conditioning, from hard street and circuit cars through to full drag applications. For builds chasing maximum top-end power, shorter billet TGVs are available to further optimise the runner length. Custom throttle flanges are available on request.
