Walker Products 91-114 Nitrogen Oxide (NOx) Sensor Bung

Walker Genuine OE Nitrogen Oxide (NOx) Sensor Bungs are authentic, original equipment components designed to provide a precise and secure mounting point for NOx sensors in vehicle exhaust systems. Sourced directly from OE manufacturing lines, these bungs are built to the exact thread, bore, and dimensional tolerances required by engine and emissions calibration teams. Unlike aftermarket approximations, Walker Genuine OE bungs ensure the sensor sits at the correct depth and orientation within the exhaust stream—maintaining accurate gas sampling and data reporting to the engine control module (ECM). Constructed from high-temperature corrosion-resistant steel, these components are engineered for long-term durability in harsh under-vehicle environments. Proper bung design is critical to maintaining emissions compliance, preventing exhaust leaks, and ensuring that NOx sensors function as intended over the vehicle’s service life. Whether used for sensor replacement, exhaust repair, or diesel aftertreatment service, Walker Genuine OE NOx Sensor Bungs deliver exact fit and trusted factory-grade quality.
