Keep Your 2016 Duramax Running Clean and Efficient
The Pollak 66-010 Downstream Nitrogen Oxide (NOx) Sensor is a premium replacement component engineered for 2016 Chevrolet and GMC trucks with the 6.6L Duramax Diesel engine. Located in the downstream (Position 2) exhaust path, this sensor is vital for monitoring the efficiency of your Selective Catalytic Reduction (SCR) system. It ensures your truck meets strict emissions standards while preventing power loss and "limp mode" conditions caused by faulty sensor readings.
