GFB Mach 2 Recirculating Plumb Back BOV - Kia Stinger GT (CK)
GFB built the Mach 2 around its proven TMS technology, giving you a direct bolt-on upgrade for the Kia Stinger GT that restores boost up to 30% faster than the factory diverter valve. It's a straightforward, no-fuss valve for owners who want sharper throttle response without changing how the car sounds.
This listing covers the Kia Stinger GT CK chassis (3.3L, 2017-2021) in the 100% recirculating plumb back configuration, SKU T9112. This version replaces the factory bypass valve directly with no adaptors or extra parts required, keeping the OEM recirculating operation but with far better response. If you want some venting noise added later, GFB's separate Atmosphere Conversion Kit can convert this valve down the track.
Key Features
- Direct bolt-on replacement for the factory bypass valve
- TMS technology for up to 30% quicker boost recovery on gear shifts
- Effectively unlimited boost holding capacity
- 100% recirculating (plumb back) design for stock-like noise levels
- No tuning, adaptors or vehicle modification required
- Upgradeable to atmosphere venting via optional conversion kit
Vehicle compatibility, OEM part numbers, and fitment notes are provided in the tabs above. Please confirm your Stinger's model year and drivetrain configuration before ordering.
