Precision Works Top Feed TGV Housing Subaru WRX STI

Precision Works Top Feed TGV Housings – Subaru WRX / STI / Legacy GT / Forester XT

Improve airflow through your Subaru EJ intake system with the Precision Works Top Feed TGV Housing Kit. Machined from billet 6061 aluminum, these housings replace the factory TGV/runner assemblies with a purpose-built performance design intended to improve airflow into the cylinder heads.

For modified EJ engines—especially builds running larger turbochargers, upgraded intercoolers, higher-flow fuel systems, or increased boost—the factory intake tract can become another area worth addressing. The Precision Works housings provide a clean, direct-fit solution while also converting the engine to a top-feed fuel rail configuration.

Each housing is precision CNC-machined for consistent fitment and finished in anodized silver for corrosion resistance and a clean appearance in the engine bay.

Fuel Rail Compatibility

These housings are designed around a top-feed fuel rail setup. Precision Works Top Feed Fuel Rails are available separately and are an excellent option for completing the installation.

When planning your fuel system, be sure to verify compatibility between your injectors, fuel rails, fuel lines, regulator, and the rest of your fuel delivery system.

A Solid Upgrade for Modified EJ Builds

For an EJ build where airflow and fuel capacity are becoming increasingly important, upgrading the TGV housings is a logical addition to the intake and fuel system. The billet construction provides a substantial, purpose-built replacement for the factory assemblies while giving you the flexibility to build a higher-capacity top-feed fuel system around your power goals.

Whether you're putting together a responsive street car, track build, or higher-horsepower turbo setup, the Precision Works Top Feed TGV Housings provide a straightforward foundation for improving the intake side of your EJ engine.
