Direct-Fit Blow-Off / Diverter Valve with Adjustable Venting Bias

The GFB Respons TMS T9010 is built as a bolt-on upgrade for Hyundai i30 N and other listed 2.0T-GDI turbo vehicles. It replaces the factory bypass valve with a stronger, performance-focused valve that gives you control over how boost is released.

Adjust the Sound Without the Usual Drawbacks

Instead of being locked into either full recirculation (quiet) or full atmosphere venting (loud), the Respons lets you set the venting balance. You can run it close to factory behaviour or dial in more blow-off sound, depending on your setup and preference.

Sharper Response Between Gear Changes

The valve is designed to vent only what’s needed, helping the turbo recover boost faster after throttle lift. The result is improved throttle response and a more consistent feel during spirited driving.

Direct-Fit for the Factory Location

This is not a universal weld-on valve. The T9010 is made to fit in the original mounting position on the compatible vehicles listed below.

Made for Real-World Driving

Suitable for daily driving and modified builds, the Respons TMS design aims to keep drivability stable while providing stronger boost control and tunable sound.
