Billet TGV Delete Kit (67mm)

The Process West Billet TGV Delete Kit eliminates the factory tumble generator valves, removing a significant restriction from the intake path and maximising airflow under all operating conditions.

Precision machined for performance.

The port profile is machined to suit ported cylinder heads, ensuring a smooth, unrestricted transition from plenum to head. The upper flange surface is O-ringed for a reliable, leak-free seal against both stock and aftermarket plenums.

67mm length.

The shorter of the two available lengths, the 67mm version is specifically required when fitting a Process West Billet Plenum to a GC8. For builds not requiring the shorter length, the 79mm version is also available.

Injector and fuel rail compatibility.

Injector ports are machined to accept both 11mm and 13mm diameter injectors without adaptors. Simply use the supplied Viton O-rings to suit your injector size. Fuel rail mounting points match the factory specification, making the kit compatible with stock and aftermarket fuel rails alike.

A precise, well-engineered upgrade for any serious Subaru build looking to remove intake restrictions and support higher power levels.
