Product Information
Enhance the driving experience of your 2019+ Mercedes-Benz G500/G550 W463A M176 4.0L BiTurbo with the BlackBoost FTA (Free-to-Air) Blow Off Valve Adapter Kit. Designed for enthusiasts who want the unmistakable turbo blow-off sound without compromising factory reliability, this precision-engineered adapter converts the factory diverter valve into a free-to-air blow off valve by venting excess boost pressure directly into the atmosphere.
Unlike the factory system, which recirculates compressed air back into the intake, the BlackBoost FTA Adapter releases boost pressure externally, producing the iconic blow-off sound while maintaining dependable turbo operation. Engineered for seamless integration with the factory diverter valve, this kit installs without permanent modifications and retains OEM functionality.
Manufactured from high-quality 6 Series CNC-machined aluminum, the adapter offers exceptional durability, corrosion resistance, and a precise fit. Installation is completely plug-and-play, requiring no ECU tuning and producing no check engine light, making it an ideal performance upgrade for daily-driven and modified G-Class vehicles alike.
Whether youre looking to enhance your Mercedes G500 or G550 with a more engaging driving experience or simply enjoy the signature turbo sound, the BlackBoost FTA Adapter Kit delivers premium quality, reliability, and performance.
