The NGK direct-fit oxygen sensor for BMW 335i xDrive (2011–2013) supplies precise closed-loop air-fuel feedback to the ECU to support engine performance, fuel economy and emissions control. Built by NTK, a ceramics-focused OEM supplier, the sensor employs an advanced ceramic sensing element with a 3-stage contaminant-resistant plasma-jet and deposit-trap overcoat to reduce element poisoning and enhance resistance to failure.
