The NGK direct-fit oxygen sensor for Toyota 4Runner (1993–2000) provides the closed-loop oxygen feedback the ECU needs to manage air–fuel ratio, fuel efficiency and emissions. Backed by NTK’s sensor technology and manufacturing, it uses an advanced ceramic element with a 3-stage contaminant-resistant plasma jet and deposit trap overcoat to reduce element poisoning and improve long-term reliability.
