The NGK direct-fit oxygen sensor for Mazda 626 (2000–2002) returns OE-style oxygen sensing to the ECU for closed-loop fuel control and diagnostic monitoring. Leveraging NTK's sensor development, the unit features an advanced ceramic element with a three-stage contaminant-resistant plasma jet and a deposit-trap overcoat that protects against element poisoning and enhances resistance to failure for reliable performance across the supported model years.
