Overview

RennTech's Blow-Off Valve adapters for the 2017-2019 GLS 450 BiTurbo bolt in to release excess boost pressure and give the engine its well-known blow-off sound. They are CNC machined from 6061-T6 aluminum, black anodized and laser etched, and because they keep the factory electronic diverter valves, they do not set a check-engine light.
