The NGK direct-fit oxygen sensor for Chevrolet Classic (2004–2005) provides constant closed-loop feedback to the engine control unit to help control air–fuel ratio, improve fuel efficiency and reduce emissions. Built on NTK ceramic sensor technology, the unit features a 3-stage contaminant-resistant plasma-jet plus a deposit-trap overcoat that protects the ceramic element from poisoning while supporting OE application development.
