RennTech's 3rd Generation Diverter Valve for the M157 5.5L V8 BiTurbo features an all-new Blow-Off Valve implemented into the re-designed OEM turbo tubes.The Diverter Valve releases the boost in high-boost situation and/or boost spikes. This especially helps during the shifting process, for faster shifting and a quicker boost response for the next gear. It helps to eliminated the so called 'Boost Lag'.

With the installation of the RennTech Diverter Valve, we are able to supply the engine with more boost pressure in order to gain higher HP numbers. Please see the RennTech R1 Package for the M157 engine for the perfect combination of the RennTech ECU Upgrade and Diverter Valve.The turbo tubes are ceramic coated in titanium to sustain high temperature and provide a more aesthetic look in the engine bay.


This Diverter Valve Upgrade requires an additional core charge, which will be credited upon return of OEM pipes and Vacuum Lines to RennTech.
