The IAG CNC Billet
Aluminum TGV Housings are one the easiest ways to eliminate the OEM tumbler
generator valves on your turbocharged Subaru engine. Our TGV housings are CNC
machined from aluminum and are able to accept all OEM specific fuel rails, most
aftermarket fuel rails, and injectors. Each TGV housing set includes lower
gaskets for the cylinder head mounting location. IAG also includes specific
hardware based on your use of optional 3mm phenolic spacers, optional 8mm
phenolic spacers or simply using OEM style gaskets. The IAG 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.
*ECU calibration is required.
