New Release! Process West Billet TGV Delete Housings with Dual Fuel Rails

Take your Subaru build to the next level with the latest release from Process West – precision-engineered billet TGV (Tumble Generator Valve) Delete Housings. Designed for enthusiasts chasing serious performance, these housings are built to maximize airflow, provide superior sealing, and support advanced dual-fuel setups.

Factory TGV assemblies restrict air flow into the cylinder heads. Deleting the valves removes bottlenecks and enables proper air flow for serious street or track performance. The dual injector setup allows for massive fuel supply for high horsepower builds.

Technical Notes:

• Aftermarket ECU and professional tuning required for dual-injector operation.
• Custom fuel plumbing is necessary to integrate the dual-rail system.
• Due to second fuel rail sitting higher than factory it will be necessary to relocate and reroute existing components and plumbing dues as coolant expansion tanks and turbo inlets (for rotated kits).
• Compatibility varies by Subaru model/engine; verify fitment for your application.
