The NTK/NGK direct-fit oxygen sensor for Nissan 200SX (1986–1987) restores continuous closed-loop feedback to the engine control unit to help maintain proper air–fuel ratio and emissions. NTK is a major OEM supplier and controls ceramic element manufacture from raw material through finished product. The sensor incorporates a 3-stage contaminant-resistant plasma jet and deposit-trap overcoat to shield the ceramic element from poisoning and increase reliability.
