Direct-Fit Replacement for Cummins Applications
The MCT CM6874 is an aftermarket NOx sensor designed as a direct-fit replacement for Cummins diesel engines, supporting the outlet (downstream) position in SCR-equipped systems. Manufactured by MCT Technic, it delivers the same fit and performance as original equipment at a lower aftermarket price point. The sensor provides accurate nitrogen oxide measurement to help maintain emissions compliance, precise DEF dosing, and smooth aftertreatment operation. Cross-references include Cummins 4326874, 4326874RX, and 2872946.
Built for Accurate Emissions Control and Uptime
Engineered for heavy-duty environments, the CM6874 is designed to withstand high exhaust temperatures, vibration, and contamination typical of on‑highway and vocational duty cycles. Consistent signal quality enables the ECU to control the SCR system effectively, helping reduce nuisance fault codes and derates tied to emissions feedback. The plug-and-play harness and connector retain OEM-style routing for quick serviceability, making this sensor a cost-effective option for fleets seeking reliable performance without sacrificing measurement accuracy or durability.
Compatibility and Cross-References
Intended for Cummins ISC/ISL engine platforms using SCR aftertreatment, this outlet-position sensor is suitable for fleet maintenance and individual repairs requiring an OEM-equivalent replacement. Aftermarket cross-references include Automann 577.90549, Dinex 5EL005, and Dorman 904-6013. California Proposition 65 warning applies.
