Hybrid Dual Outlet Blow-Off / Diverter Valve Kit for Nissan GT-R R35

The GFB T9205 Twin Hybrid Dual Outlet Valve Kit brings iconic dual-port venting technology to the Nissan GT-R R35 VR38DETT. Engineered to handle high boost and offer configurable venting, this kit balances performance, response and sound in a direct bolt-on solution.

Configurable Venting Modes

The Hybrid design allows three venting options:

• Full Recirculation — OEM-style operation with minimal noise
• 50/50 Venting — Balanced atmosphere and recirculation
• Full Atmosphere — Louder blow-off sound for performance focus

Progressive Valve Action

The staged outlet design opens the recirculation port first, maintaining smooth airflow and engine behavior, and then progressively opens the atmosphere port as boost pressure increases. This reduces hesitation and improves response under load compared to simple vent-to-atmosphere alternatives.

Enhanced Boost Control & Durability

By improving boost holding and response during throttle modulation and gear changes, the T9205 enhances performance on both stock and modified GT-R R35 vehicles. Precision machining and durable materials ensure long-lasting reliability under repeated heat and pressure cycles.
