Weistec Anti Surge Valve | Water-Methanol Injection System Mercedes-Benz G63 AMG | G63 AMG 6X6 Twin Turbo 5.5L V8 M157 2012-2016 for 2012-2016 Mercedes-Benz G63 AMG 01-157-01763-1 | Vivid Racing

Weistec ASV/WM Injection System for M157 BiTurbo 5.5L Engine

The Weistec ASV/WM Injection System is designed to enhance your driving experience with the M157 BiTurbo 5.5L engine by incorporating several key components. One of the standout features is the Weistec Anti Surge Valve (ASV). Unlike the factory setup, which lacks a bypass valve, our system helps prevent compressor surge that can occur when the throttle closes after a burst of acceleration. This surge can be harmful to your turbochargers, and avoiding it is essential for maintaining optimal performance.

How It Works

The Weistec ASV operates using engine vacuum, opening up when the throttle closes. This allows the compressed air to vent to the atmosphere rather than backflowing into the compressor housing, which can stall the compressor wheel. Plus, you'll enjoy that signature "blow-off" sound that many turbocharged vehicles are known for! This product is specifically tailored for larger SUVs equipped with either the M157 or M278 engines. Make sure to check our Vehicle Application Data above to confirm fitment.

Easy Installation

This system is a complete, bolt-on package that eliminates the guesswork and need for custom fabrication. Weistec has meticulously engineered and manufactured many components of this system to ensure a straightforward installation process. The performance gains and reliability make this upgrade a must-have for M157 engine owners.
