Product Description

The GFB T9661 DVX is a fully direct-bolt replacement diverter valve engineered for modern Hyundai and Kia turbo vehicles. It replaces the weaker factory valve, improving boost holding and throttle response. Its dual-port design and patented Venting Bias Adjustment let you dial the blow-off sound from quiet recirc to loud atmosphere - perfect for enthusiasts seeking both performance and aggressive audio cues.

Featuring TMS (Turbo MotorSport) technology and ECU-controlled pilot actuation, the DVX opens quicker during throttle lifts, reducing lag and preserving boost. Installation is easy: bolt it on using the included screws and replace the vacuum hose - no tuning changes required. Fitment is confirmed up to 2019; 2020-2025 coverage is unconfirmed at the time of listing.
