NGK Direct Fit Oxygen Sensor - Acura NSX (NA2) 1997-1999

A direct-fit oxygen sensor built on NTK's advanced ceramic sensing element, the OE sensor technology found on a large share of the world's vehicles. A contaminant-resistant plasma-jet and deposit-trap overcoat shields the element from poisoning, and constant closed-loop feedback to the ECU holds the air/fuel ratio in range while flagging OBDII faults in fuel delivery or catalytic converter efficiency. It ships with the correct OE-style connector for a bolt-in replacement with no splicing.
