NGK Honda Civic 2005-2003 Direct Fit Oxygen Sensor

If you're working on a 2003-2005 Honda Civic and need to replace the oxygen sensor, this direct-fit part from NGK is a solid option. Oxygen sensors are a key part of your car's onboard diagnostic system. They help the engine computer keep the air-fuel mixture just right for the best engine performance, good gas mileage, and to keep harmful emissions down. This sensor sends constant feedback to the ECU, and it also helps alert you if there's an issue with fuel delivery or the catalytic converter.

NGK, a major supplier of original equipment sensors, builds these with an advanced ceramic sensor element. This element has a special three-stage coating that acts as a trap for contaminants and a plasma jet, which helps protect it from poisoning. This means the sensor is better protected against things that can cause it to fail prematurely, helping to ensure it works reliably over time.
