Direct-Fit Blow-Off / Diverter Valve with Adjustable Sound

The GFB Respons T9011 is designed for selected Hyundai and Kia 1.6T-GDI turbo vehicles as a direct replacement for the factory diverter valve. It upgrades the factory unit with a robust valve body and an adjustable venting system that lets you tailor both performance feel and sound.

Sound Adjustment System

Unlike fixed diverter valves, the Respons T9011 allows you to control how much air is recirculated back into the intake versus vented to atmosphere. This lets you keep factory-quiet operation or introduce a stronger blow-off sound without sacrificing drivability.

Sharper Throttle Response

By managing boost pressure release more efficiently during throttle lift, the valve helps the turbocharger recover boost more quickly between gear changes, improving throttle response compared with the standard factory valve.

True Bolt-On Installation

The T9011 installs in the original valve location using factory mounting points. No cutting, wiring, or fabrication is required on the compatible vehicles listed below.

Built for Daily and Performance Use

Designed to handle repeated heat cycles and boost pressure, the Respons T9011 is suitable for daily-driven vehicles as well as lightly modified performance setups.
