IAG CNC TGV HOUSINGS 15 - 20 WRX (WITHOUT REFERENCE PORT)
The IAG Performance 2015 - 20 WRX TGV Housings are one the easiest ways to eliminate the OEM tumbler generator valves on your turbocharged Subaru FA20 DIT engine. Our latest design featured here offers all the traditional performance benefits of IAG's Housings without the additional reference port/plug used on earlier versions. IAG's WRX TGV housings are CNC machined from billet aluminum and feature an engraved IAG Logo. The WRX TGV Housings do not require porting modifications, cores, or damage to your original OEM parts in case you ever need to return the vehicle to stock. The TGV housings are a simple install requiring only basic hand tools and roughly 30 minutes of time.
*ECU calibration is required. Possible engine damage may occur without immediately calibrating the ECU after installation.
