Exergy CP4 Saver Improved Stock Inlet Metering Valve For 2011-2016 LML Duramax

Protect your 2011–2016 Chevy or GMC 6.6L LML Duramax from catastrophic CP4 pump failure with the Exergy System Saver Inlet Metering Valve. This upgraded FCA/MPROP features a robust stainless steel construction and a dual-layer 10-micron screen that far outperforms the OEM’s 85-micron single-layer design. In the event of a CP4.2 failure, this screen helps contain debris before it contaminates your injectors and fuel system, reducing repair costs by potentially thousands of dollars.

Exergy’s proven design not only safeguards your injectors but also helps eliminate common CP4 issues such as idle surge and high rail pressure fluctuations. Engineered for direct replacement, this valve fits seamlessly in place of Bosch part numbers 0 928 400 779 and 0 928 400 757, GM 12641035, and ACDelco 12641035. Flow-tested and performance-ready, it’s a smart preventative upgrade for any LML Duramax owner.
