GFB Replacement BOV Standard Spring - Respons TMS/Deceptor Pro II/Mach 2 - Universal
GFB has built a reputation for engineering blow off valves that seal properly and respond instantly, and this standard spring is the factory fitted tune for their Respons TMS and Deceptor Pro II valves. It's also available as an upgrade option for the Mach 2 when configured for atmosphere venting, giving you the correct spring rate to match your engine's vacuum characteristics.
This listing covers the standard rate replacement spring for the Respons TMS, Deceptor Pro II and Mach 2 valve range. It's a universal fit part, sold as a single item (SKU 6115) rather than a per vehicle kit.
Note: Use this spring only where the valve is set up for atmosphere venting and engine idle vacuum is above 64 kPa (19 inHg). For full recirculation setups or lower idle vacuum, GFB's softer spring (SKU 6116) is the correct choice.
Key Features
- Standard rate spring as originally supplied in Respons TMS and Deceptor Pro II valves
- Optional upgrade spring for Mach 2 valves set up for atmosphere venting
- Suited to atmosphere venting applications with idle vacuum above 64 kPa (19 inHg)
- Direct fit replacement part, no modification required
Vehicle compatibility, valve compatibility, and setup notes are provided in the tabs above. Please confirm your valve model and venting configuration before ordering.
