Process West was established in 2003. The business has seen continual rapid growth and we now have approximately 95 distributor/resellers worldwide. In April 2012 we moved from our old 180m2 workshop to our brand new 900m2 factory. We specialise in the design, engineering and manufacture of small heat exchange products and other aluminium products for the automotive industry. Managing director Kevin Westblade has been designing cooling, intake and fuel systems for 25 years. With years of experience in the heat exchanger industry and traveling around the world to various heat exchanger manufacturing plants means that Process West uses only the absolute best available heat exchanger core and manufacturing processes. We use the latest state of the art tig welding equipment and HAAS CNC vertical milling and lathe machines

The Process West range billet manifolds is a no holds barred manifestation of what is possible under the hood of a STI when perfect aesthetics meet high end performance. What you see here is the result of years of research and testing, multiple prototypes and a ground up redesign of the original ground breaking "Corsa Veloce" product range. Available in two major configurations they feature a full billet plenum with generous billet bell mouths and thick wall polished CNC mandrel bent tube components. High end TIG welding assembly makes them suitable for up to 100psi boosted applications. No other product comes close to this level of strength and detail. The range is modular to suit everything from MY99 GC8 to the latest STI's with any stock throttle or that to suit the 3" Hypertune billet throttle. Custom throttle flanges are available on special request.

This is the pinnacle of induction systems for the Subaru STI range. The plenum volume and runner length combination has been optimized for brutal low and mid range torque while increasing top end power aggressively. We've had customers pull off other aftermarket intake manifold systems to install this as performance is unmatched. Gains on even a stock setup are quite high at 10%+ however we recommend the Track version manifold for any performance setup not requiring AC up to the most extreme track and drag cars. For cars requiring even more power in the upper rev range the track version can be supplied with shorter billet TGV's (lower runner section).
