The NGK direct-fit oxygen sensor for BMW 525i (1991–1995) provides the ECU with closed-loop feedback to help control air–fuel ratio, maintain engine performance and improve efficiency while reducing emissions. NTK's ceramics-based sensor uses a 3-stage contaminant-resistant plasma jet and deposit-trap overcoat to protect the sensing element from poisoning. NTK works with OEMs throughout development to enhance durability and failure resistance.
