The NGK direct-fit oxygen sensor for Toyota Celica (2003–2005) provides OE-style oxygen monitoring to the on-board diagnostic system so the ECU can regulate air–fuel ratio, improve fuel efficiency and reduce emissions. NTK, a ceramics specialist and OEM supplier, uses a 3-stage contaminant-resistant ceramic element with a deposit-trap overcoat to guard against element poisoning and improve resistance to failure while matching OE fit and performance.
