NEW! The OEM Subaru intake manifold features “Tumble Generator Housings,” which are designed to decrease cold start emissions by “tumbling” 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. IAG has completely redesigned their popular TGV housings with new port shapes to further improve airflow and allow for the OEM emissions equipment compatibility. They have seen gains of 5 wheel horsepower over the V2 TGV housings, and 13 WHP over stock housings.
Because the V3 Top Feed TGV Housings maintain compatibility with the OEM emissions components, there is no need to have the vehicle custom tuned if only the TGV Housings are installed. These TGV housings provide additional clearance for larger inlet turbochargers. When used in combination with other performance modifications professional calibration is recommended. Please note that these TGVs are not compatible with fuel lines that require removal of the TGV motors.
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 top-feed 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.
NO TUNING REQUIRED.
