Process West Intake Manifold Track Version Reverse Throttle Position Subaru STI 2004+

Part #: PRW - PWIM001. The Process West billet intake manifolds are a top - notch addition for your WRX/STI. After years of research, testing, and multiple prototypes, these manifolds are a total redesign of the original 'Corsa Veloce' range. Available in two setups, they have a full billet plenum with large billet bell mouths and thick - wall polished CNC mandrel - bent tubes. High - end TIG welding makes them strong enough for up to 100psi boosted applications. This is the best induction system for Subaru WRX/STI. The plenum volume and runner length are optimized for strong low - and mid - range torque and increased top - end power. Many customers replace other aftermarket intake manifolds with this one due to its unmatched performance. Even on a stock setup, you can see over 10% gains. They suggest the Track version for performance setups without AC, from regular to extreme track and drag cars.

Using this intake manifold is straightforward. First, make sure your car is turned off and cooled down. Remove the old intake manifold carefully following your car's service manual. Then, install the Process West intake manifold in its place, ensuring all connections are tight. When it comes to maintenance, regularly check for any loose connections or signs of damage. Keep the manifold clean by using a soft cloth and a mild cleaner. Avoid using harsh chemicals as they may damage the surface. If you plan to boost your car up to 100psi, ensure your car's other components can handle the pressure. Also, note that this Track version is recommended for setups without AC, so if your car has AC, consider other options.
