The NGK direct-fit oxygen sensor for Scion xA (2004–2006) provides continuous air-fuel ratio feedback to the ECU to support efficient combustion and emissions control. Produced by NTK, a major OEM sensor and ceramics manufacturer, the unit uses an advanced ceramic sensing element with a three-stage contaminant-resistant plasma jet and deposit-trap overcoat to resist element poisoning and align with OEM performance standards.
