The NGK direct-fit oxygen sensor for BMW 325i (1987–1988) provides the ECU with closed-loop feedback to help control air–fuel ratio, preserve engine performance and reduce emissions. NTK's ceramics-based sensor element features a 3-stage contaminant-resistant plasma jet and deposit-trap overcoat that protects the element from poisoning. NTK works with OEMs through development to enhance durability and resistance to failure.
