New Provisions Racing has IAG TGV deletes. These delete kits will get rid of the restrictive butterfly valves installed by the factory. These valves are found within the tube channeling the engine’s intake air from the plenum to the intake terminal. When factory TGV is eliminated, the flow of intake air is no longer restricted, allowing it to advance toward the cylinders. New Provisions WRX TGV delete kits are compatible with OEM Subaru parts as well as factory gaskets and intake manifolds.

IAG TGV Deletes and WRX TGV delete kits are made for the advancement of air flow for engine performance. Doing so by ridding the diverter and matching the port of the OE lower riser to the OEM cylinder heads.

In approximately one to two hours, these TGV housings can be installed using standard hand tools. However, to prevent damage to the engine, following installation, you will be required to do ECU calibration.
