GFB Replacement BOV Standard Spring - Suit Respons/Deceptor Pro/Mach 2 (Plumb Back)
GFB builds its blow off valves around precise spring tuning, so swapping to the correct spring rate keeps the valve responding exactly as it should under boost and on lift off. This softer spring is the factory fitment inside the Mach 2 when running fully recirculated, and it's available separately for owners who need to match their valve's spring rate to their plumbing setup.
This listing covers the replacement standard spring for GFB's Mach 2, Respons TMS, and Deceptor Pro II valves in plumb back configuration. SKU 6116.
Important: only fit this softer spring to Respons TMS and Deceptor Pro II valves when fully recirculated and/or engine idle vacuum is below 64 kPa (19 inHg). For atmospheric venting with idle vacuum above this figure, use the standard spring (SKU 6115) instead.
Key Features
- Softer tension spring for plumb back BOV configurations
- Factory standard fitment inside fully recirculated Mach 2 valves
- Compatible replacement for Respons TMS and Deceptor Pro II valves
- Suited to low idle vacuum and full recirculation setups
Vehicle compatibility, OEM part numbers, and fitment notes are provided in the tabs above. Please confirm your valve model and plumbing configuration before ordering.
