Direct-Fit Blow-Off / Diverter Valve for Nissan GT-R R35

The GFB Respons TMS T9005 replaces the factory bypass valves on the Nissan GT-R R35 VR38DETT with a performance-oriented unit featuring GFB’s patented adjustable venting bias system. This allows you to tune how boost pressure is released from the intake system when lifting off the throttle.

Adjustable Venting Bias System

Unlike fixed blow-off valves, the T9005’s ventilated bias adjustment lets you control how much air is recirculated versus vented to atmosphere. This gives you a wide range of sound and behaviour options — from quiet and refined to more audible atmospheric venting, depending on your preference.

Improved Throttle Response

By venting boost pressure efficiently and only when needed, the valve supports faster boost recovery between gear changes and a more responsive throttle feel compared with many factory-style diverter valves.

True Direct-Fit Installation

This valve is designed to mount directly in the factory diverter location on the Nissan GT-R R35, using the original mounting points and hose connections with no cutting or fabrication required.

Built for Performance and Daily Use

Constructed with robust materials and engineered for repeated thermal cycles and pressure events, the Respons TMS T9005 provides both performance capability and reliable everyday drivability.
