The NGK direct-fit oxygen sensor for Nissan Altima (2002–2004) provides precise closed-loop air–fuel feedback to the engine control unit, helping maintain optimal engine performance, maximize fuel efficiency and reduce emissions. NTK ceramic sensing technology uses a 3-stage contaminant-resistant plasma-jet and deposit-trap overcoat to protect the element from poisoning, and designs are refined with OEM partners to improve resistance to failure.
