Show original supplier description
The GFB Mach 2 (Part No. T9114) is a high-performance recirculating diverter valve from MODE Auto Concepts, utilizing GFB's proprietary TMS technology. Unlike atmospheric blow-off valves, the Mach 2 operates as a 100% recirculating (bypass) valve, ensuring performance gains without unwanted noise, making it an ideal choice for a stealthy modification. The Mach 2 is designed to overcome the limitations of factory bypass valves, which can sometimes be designed to vent boost pressure above a certain threshold to protect the engine or are not optimized for throttle response. The Mach 2 features a pressure-balanced design capable of holding unlimited boost and its TMS technology specifically enhances throttle response. Installation is straightforward as it is designed as a direct factory replacement, requiring no additional adaptors or vehicle modifications. This specific model is confirmed to fit the following Hyundai and Kia vehicles: HYUNDAI i30/Elantra N-Line Sedan (2021-on, Smartstream engine G4FP), HYUNDAI Kona N Line 1.6T-GDI (2020-on, Smartstream engine G4FP), HYUNDAI Sonata N-Line 2.5 T-GDI (2020-on), and HYUNDAI i20N 1.6T-GDI Smartstream (2020-on).
