Function of this part
The EGR (exhaust gas recirculation) system routes a controlled amount of exhaust gas back into the intake. This lowers combustion temperatures and helps reduce NOx emissions.
Why this part matters
Because EGR flow is monitored closely by the engine management system, issues with EGR valves or coolers quickly trigger fault codes and derates. Keeping the EGR system in good working order is key to reliability and emissions compliance.
About the brand
Cummins engine parts are trusted for reliable power in a variety of heavy-duty truck and equipment applications.
