Process West Intake Manifold | 2006 – 2021 Subaru WRX/STI (PWIM001)

Description:

Intake Manifold for 2006 - 2021 Subaru WRX & WRX/STI by Process West

The Process West range billet manifolds is a no holds barred manifestation of what is possible under the hood of a WRX/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 fully featured design process that makes this a key asset of our 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 application.

This is the pinnacle of induction systems for the Subaru WRX/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 Process West recommends 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).
