Process West Billet TGV Delete Kit (WRX 01-07/STi 01-21) – Black In Demand

Description

*Note: 08-14 WRX not compatible with stock manifold, requires STI or Process West manifold*

With the port profile machined to suit ported heads these are a simple upgrade to maximise airflow in all conditions. The upper flange surface is O-ringed for a perfect seal to either a stock or aftermarket plenum. Fuel injector ports are machined in such a way that either 11mm or 13mm diameter top-feed injectors will seat without needing any adaptors, just use the supplied Viton O-rings as required. Fuel rail mounting points are the same as stock, so it is possible to use this with other aftermarket fuel rails.
