NGK 5‑wire wideband air‑fuel ratio sensor for Audi A3 (2006–2013) applications supplies a direct-fit linear AFR signal so the engine control unit can precisely manage fuel mixture for efficient, cleaner combustion. NTK's OEM-scale sensor engineering is applied here, using advanced ceramic materials and a 3-stage contaminant‑resistant plasma jet and deposit‑trap overcoat to protect the sensing element and improve resistance to failure.
