Process West Intake Manifold - Subaru WRX (VB) FA24
The Process West Intake Manifold was the first aftermarket manifold developed for the FA24 engine in the Subaru WRX (VB). It combines a billet plenum, cast large bore runners and a working billet TGV section for higher intake flow. On Process West's modified test car it lifted power from 246kW to 275kW at the wheels, with about 10% more torque from 2500 to 6500rpm.
Standard (PWIM010) suits most builds. Port Injection (PWIM010PI) adds four port injector mounts for high-power builds.
Note: A front mount intercooler is required, as top mount intercoolers will not fit the new throttle position. Many front mount kits, including earlier Process West kits, also need the Throttle Adaptor Pipe (PWIM010AP). Installation by a professional is recommended.
Features
- Billet plenum with cast large bore runners
- Computer-designed internal porting and larger plenum volume
- Fully working billet TGV section, as the factory TGVs are built into the manifold
- Part of the Process West no check engine light range
- Optional TGV delete parts available (PWTD07)
