NGK Nissan Altima 2004-2002 Direct Fit Oxygen Sensor

This is a direct fit oxygen sensor from NGK for your 2002-2004 Nissan Altima. Oxygen sensors are a key part of your car's onboard diagnostic system, helping to keep the engine running at its best. They provide feedback to the engine computer about the air-fuel mixture, which is crucial for maximizing fuel efficiency and reducing emissions. A properly working sensor also alerts you if there are issues with fuel delivery or the catalytic converter.

NGK, a major OEM supplier, builds these sensors with an advanced ceramic element. This element features a special coating designed to protect it from contaminants and deposits, which can cause other sensors to fail prematurely. Because NGK controls the ceramic element from raw material to the finished product, they can ensure a well-built sensor that works reliably with your Altima's specific engine management system.
