The NGK direct-fit oxygen sensor for Mazda 6 (2003–2008) provides OE-equivalent oxygen sensing across a broad model range, delivering continuous closed-loop feedback to the ECU to help maintain proper air-fuel ratio and support OBDII diagnostics. NTK's advanced ceramic element uses a three-stage contaminant-resistant plasma jet and deposit-trap overcoat to reduce element poisoning and improve resistance to failure for durable, OEM-style operation over the covered years.
