Ruian Wego Auto Parts Introduces New Cummins NOx Sensors 5491423 & 5491422

Ruian Wego Auto Parts Co., Ltd, a professional manufacturer and supplier of automotive aftermarket components based in Ruian, China, is proud to announce the launch of two new high-quality NOx sensors — Cummins 5491423 and 5491422. These new products are precision-engineered for diesel vehicle SCR (Selective Catalytic Reduction) aftertreatment systems and are now available for the European, North American, and South American markets.

Precision Engineered for Diesel SCR Aftertreatment

The new Cummins 5491423 and 5491422 NOx sensors are designed to continuously monitor nitrogen oxide (NOx) concentration in the exhaust stream, giving the engine control unit (ECU) the accurate feedback it needs to optimize AdBlue (DEF) dosing. Accurate NOx measurement is critical to SCR efficiency, fuel economy, and compliance with modern emissions regulations such as Euro 6 and EPA standards. Built to perform in the harshest under-hood and exhaust conditions, these sensors deliver fast response, stable signal output, and long service life.

Key Product Highlights

• High quality construction: durable ceramic sensing element, corrosion-resistant housing, and high-temperature stability for demanding diesel environments.
• 15-month warranty: every unit is backed by a full 15-month quality warranty, reflecting our confidence in product reliability.
• OE-compatible fit: direct replacement design with OE-matched connectors for easy, plug-and-play installation.
• Wide vehicle compatibility: suitable for heavy-duty commercial trucks, buses, and light-duty passenger diesel vehicles.
• Quality tested: each sensor is inspected for accurate measurement, fast response time, and consistent performance.
