Here, you are looking at the Process West Track Version Intake Manifold for the 04+ Subaru STI. This intake manifold is simply a work of art in the engine bay made using full billet aluminum construction with billet bell mouth ended runners. This intake manifold is ideal for racecars and rally cars requiring more power in the upper rev range in big horsepower builds. 

DETAILS:

• Track version
• Reverse throttle position
• Full billet aluminum plenum 
• Biller bell mouth ended runners.
• CNC mandrel bent tube components.
• Anodized black finish.
• Designed with extra vacuum provisions. 
• The manifold is the result of years of research and testing, multiple prototypes and ground-up redesign of the original groundbreaking “Corsa Veloce" product range.
• High-end TIG welding assembly makes them suitable for up to 100psi boosted applications.
• The plenum volume and runner length combination has been selected for aggressive low and mid-range torque while opening power higher in the rev range.
