The NGK direct-fit oxygen sensor supplies OE-style oxygen feedback to the ECU, helping manage air–fuel ratio for emissions control and fuel economy. NTK’s ceramic manufacturing and a three-stage contaminant-resistant overcoat with deposit-trap protection reduce element poisoning and improve durability. Application: for 1993–1997 Infiniti J30 models as a direct-fit sensor replacement aligned with OE application.
