Description

The RennTech 3rd Generation Diverter Valve is a performance upgrade for the M157 5.5L V8 BiTurbo engine. It features an all-new Blow-Off Valve integrated into re-designed OEM turbo tubes. This diverter valve releases boost during high-boost situations or spikes, aiding in faster shifting and quicker boost response for the next gear.

Installation of this diverter valve can help eliminate boost lag and allow the engine to receive more boost pressure for higher horsepower gains. The turbo tubes are ceramic coated in titanium for high-temperature sustainability and an enhanced engine bay aesthetic.
