NGK direct-fit oxygen sensor for Honda Civic (2003–2005) replaces the OE sensor to provide continuous closed-loop feedback to the engine control unit. Using NTK OE application expertise, it helps control the air–fuel ratio to support fuel efficiency and emissions reduction. The advanced ceramic sensing element features a 3-stage contaminant-resistant plasma jet and deposit-trap overcoat to guard against contamination and extend service life.
