Process West Billet TGV Delete Kit - Subaru WRX/STI (GC8) - 67mm
The Process West Billet TGV Delete Kit replaces the factory tumble generator valves on the GC8 WRX and STI in the 67mm length. The factory butterflies sit in the intake runners and are a significant restriction, and removing them lets the engine breathe freely at all times. The ports are machined to suit ported heads for a smooth path from plenum to head.
Available in a silver or black finish.
Note: The 67mm length is required when fitting a Process West billet plenum to a GC8. Installation by a professional is recommended.
Features
- Removes the restrictive factory tumble generator valves
- Port profile machined to suit ported cylinder heads
- O-ringed upper flange seals against stock and aftermarket plenums
- Injector ports take 11mm or 13mm injectors without adaptors, using the supplied Viton O-rings
- Fuel rail mounts match factory, so stock and aftermarket rails fit
