The NGK direct-fit oxygen sensor for the 2004 Volkswagen Golf restores accurate air-fuel sensing and delivers closed-loop feedback to the ECU to help maintain engine performance, fuel efficiency and emissions control. Produced by NTK, a ceramics-focused OEM sensor specialist, it uses an advanced ceramic element with a 3-stage contaminant-resistant plasma-jet and deposit-trap overcoat to protect the element from poisoning.
