NGK direct-fit oxygen sensor for Acura MDX (2003–2006) supplies continuous closed-loop data to the engine control unit to maintain proper air–fuel ratio and help manage emissions and fuel economy. Using NTK OE design practices, the sensor features an advanced ceramic element with a 3-stage contaminant-resistant plasma jet and a deposit-trap overcoat to guard the element against poisoning and extend operational life.
