The NGK direct-fit oxygen sensor for Volkswagen Jetta (1999–2005) restores precise oxygen feedback to the ECU to help control air–fuel ratio, support engine performance and reduce emissions. NTK leverages ceramics technology and ongoing design improvements for better reliability. This sensor includes an advanced ceramic element protected by a 3-stage contaminant‑resistant plasma jet and a deposit‑trap overcoat to guard against element poisoning.
