The NGK direct-fit oxygen sensor for Acura EL (2001–2003) returns precise exhaust feedback to the engine control unit to help control air–fuel ratio, improve fuel economy and reduce emissions. NTK applies ceramic manufacturing control and works with OEMs through development and production. The sensor's ceramic element features a 3-stage contaminant-resistant plasma-jet and deposit-trap overcoat to protect against element poisoning and support lasting operation.
