Process West Street Billet Intake Manifold - Subaru WRX / STI (GC8) MY99-00 - Cable Throttle Stock Orientation
The Process West Street Billet Intake Manifold suits the 1999-2000 Subaru WRX and STI (GC8) with a cable throttle in the stock orientation. Its plenum volume and runner length favour strong low and mid-range torque while freeing up the top end. Process West measured about 9% more torque and power on stock cars and on modified E85 builds.
Choose a silver or black finish.
Note: Suits 1999-2000 GC8 models with the cable throttle in the stock orientation. Plenum volume is compatible with the factory air conditioning. Installation by a professional is recommended.
