IAG V3 Top Feed TGV Housings With Butterfly Pass Thru (Black) (06-14 WRX 07+ STI 07-12 LGT 09-13 FXT)
The OEM Subaru intake manifold features “Tumble Generator Housings,” which are designed to “tumble” the airflow on cold starts. Once the cold start process is over, the butterfly valves in the housings remain in the open position and don’t restrict flow much. This means that there are airflow gains to be had, even with the butterfly valves in place. We’ve completely redesigned our popular TGV housings with new port shapes to further improve airflow and allow for the OEM emissions equipment compatibility. We’ve seen gains of 5 WHP over our V2 TGV housings, and 13 WHP over stock housings. The IAG V3 Top Feed TGV Housings are CNC machined in house from 6061 aircraft grade aluminum. Finished in natural silver, or anodized black, the TGV housings look great in the engine bay. Designed to work with all popular aftermarket or stock injectors, the housings can be used for all levels of builds and will provide increased horsepower even in stock vehicles. Our innovative design allows the housings to be used with different upper manifold bolt patterns. The custom injection molded fittings allow for installation of the OEM motors, shaft, and butterfly valves.
