The NGK direct-fit oxygen sensor for Jeep Grand Cherokee (2004) replaces the original sensor to monitor exhaust oxygen and feed continuous closed-loop information to the engine control unit, supporting fuel efficiency, emissions control and steady engine performance. Constructed with NTK ceramic sensor technology and a three-stage contaminant-resistant plasma-jet and deposit-trap overcoat, it enhances resistance to element poisoning and benefits from OEM-focused development for reliable fitment.
