Show original supplier description
The IAG Performance V3 Top Feed TGV (Tumble Generator Valve) Housings represent a fully redesigned upgrade for Subaru intake manifolds, engineered with the primary goals of improving airflow and maintaining OEM emissions compatibility. These housings feature new port shapes that increase efficiency, potentially delivering up to 5 WHP over previous IAG V2 TGV housings and up to 13 WHP over stock housings. Constructed from 6061 aircraft-grade aluminum and CNC machined in-house, these TGV housings are designed to accommodate all popular aftermarket and stock injectors. The innovative design also accounts for multiple upper manifold bolt patterns. Custom injection-molded fittings allow for the installation of OEM motors, shafts, and butterfly valves, preserving essential functionality. These IAG V3 TGV Housings are suitable for both stock and performance builds, offering noticeable power gains while preserving OEM functionality. Professional tuning is recommended when these housings are combined with other modifications for optimal results. The kit includes 2x TGV Housings, 1x Hardware Bag, and 4x Injection Molded Housing Adapters. Note that OEM emissions components are not included and must be re-used from the original parts. These housings are compatible only with single combined motor/sensor assemblies and are not compatible with separate sensor/motor assemblies found in older Subarus, nor with fuel line kits that require the removal of OEM TGV motors/sensors.
