Product Description

The GFB T9133 Mach 2 TMS is a purpose-built recirculating diverter valve featuring GFB's proven Turbo Management System. Designed as a direct bolt-on for Evolution I-X, 3000GT VR-4, Ralliart Lancer, and select Subaru models, it boosts throttle response and holds pressure more effectively than factory units. Its balanced piston can handle 100 psi+ and enables up to 30 % faster boost return during gear changes.

Made from CNC-machined aluminium with an anodised finish, the valve is durable, quiet (100 % recirc), and installs easily with no modifications. For users desiring an atmospheric blow-off sound, an optional conversion kit (part 5933) is available. Fitment is confirmed through 2016 based on manufacturer and retailer sources; compatibility beyond that is unverified at time of listing.
