The NGK direct-fit oxygen sensor for Acura MDX (2007–2009) supplies OE-style exhaust feedback to the ECU to help control air–fuel ratio, enhance fuel economy and curb emissions. NTK's sensor program applies ceramic manufacturing oversight and OEM partnerships from concept to production. The advanced ceramic element includes a 3-stage contaminant-resistant plasma-jet and deposit-trap overcoat to shield the element from poisoning and improve service life.
