Exergy Performance System Saver Improved Stock Metering Valve (FCA/MPROP), 2011-2016 GM 6.6L Duramax

Exergy Performance's improved Inlet Metering Valve is cost effective insurance for the failure prone CP4.2 pump. Exergy has developed this innovative design to help minimize further damage to the factory fuel system, which can cost many thousands of dollars. The factory 80 micron screen has proven incapable of capturing all the contaminates that can cause this, so Exergy developed this improved design to capture debris up to 25 microns. The 2 layer, double wrapped, stainless screen is the way that Exergy does this. This design will not tear or delaminate like the factory screen, and will protect fuel system part up stream to save you money. The new design will capture more debris, causing the truck to shut down sooner, creating less damage and downtime in the process.


Exergy Performance is a division of Exergy Engineering and is focused on the unique needs of high-performance diesel applications. The need for this specialized attention was recognized after assisting in root cause analysis of everything from rough idle to broken engine components caused by well-meaning, but inexperienced and/or under-equipped fuel system modifiers. Given our history in the world of diesel fuel injection, we have a distinct advantage in the areas of experience, innovation, and test equipment.
