5587015
This is an Exhaust Gas Recirculation (EGR) valve for Cummins ISB and QSB diesel engines. The EGR valve recirculates a portion of the engine's exhaust gas back to the engine cylinders to reduce nitrogen oxide (NOx) emissions. Over time, these valves can become clogged with carbon deposits or suffer electrical failure, triggering check engine lights, causing rough idling, or leading to failed emissions tests. It is commonly replaced as a remanufactured unit (often sold as kit 5587015RX) to restore proper emissions control and fuel efficiency.
Primarily listed for EPA 2017 6.7L ISB and QSB engines. Always verify base part number and engine serial number before ordering, as this listing is specifically for the new/remanufactured EGR valve assembly.
