TheiBR TGV Delete for the 2015+ WRX platform is a complete one piece TGV delete. Unlike any other product on the market these aluminum parts replace both the TGV assembly and the plastic lower section of the intake. The lower plastic divided section creates a large restriction due to both reduction in cross section as well as increasing the amount of surface area per cross section of airflow. Traditional TGV deletes only remove the main TGV assembly. This one piece replacement also reduces the amount of sealing surfaces and thus eliminates one more place for a boost leak to occur. Lower sealing surface is machined for OEM seal ring.
