Direct-Fit Twin Valve Blow-Off Kit for 3.3T Twin-Turbo Platforms

This GFB Respons TMS Stinger Direct-Fit kit is purpose-built for vehicles running the 3.3T-GDI twin-turbo engine. It includes two matching Respons TMS valves to correctly service both turbochargers without custom pipework or adapters.

Two Valves for Twin-Turbo Layout

Unlike single-valve solutions, this kit supplies two identical Respons TMS valves to replace both factory valves in twin-turbo systems. This ensures balanced operation, consistent venting, and uniform boost control across both turbos.

Adjustable Venting Bias System

Each valve features GFB’s adjustable venting bias system, allowing you to tune how much air is recirculated back into the intake versus vented to atmosphere. This lets you control blow-off sound while maintaining smooth drivability.

Improved Response and Boost Control

The Respons TMS design helps reduce compressor surge and supports faster boost recovery between shifts, delivering sharper throttle response compared with factory diverter valves.

True Bolt-On Installation

This is a genuine direct-fit kit for the vehicles listed below. It installs in the factory valve locations using original mounting points, with no cutting or fabrication required.
