NGK direct-fit oxygen sensor for 1987–1990 Jeep Cherokee is an OE-style replacement that restores closed-loop feedback to the engine control unit, helping preserve engine performance, fuel economy and emissions control. NTK’s sensor program focuses on ceramic control and OEM collaboration; the sensing element uses a 3-stage contaminant-resistant plasma jet and deposit-trap overcoat to protect the ceramic from contaminant poisoning.
