Precision Works Billet TGV Housing - Subaru WRX 2002-2007 / STI 2008-2017

Engineered for serious builds, this top-feed TGV housing kit is machined from billet 6061-T6 aluminum on a 5-axis CNC machine, then finished in anodized silver for durability and aesthetics. It replaces the restrictive OEM TGV assemblies to free up airflow to the cylinder heads, supports both 11mm and 13mm injectors, and retains factory fuel-rail mounting points.
