The NGK direct-fit oxygen sensor for Jeep Grand Cherokee (2001–2004) replaces the OE sensor to monitor exhaust oxygen and provide continuous closed-loop feedback to the engine control unit, helping maintain fuel economy, reduce emissions and stabilize engine performance. Built with NTK ceramic sensor technology and a three-stage contaminant-resistant plasma-jet and deposit-trap overcoat, it improves resistance to element poisoning and reflects OEM development for reliable fitment.
