NGK Nissan Frontier 2004 Direct Fit Oxygen Sensor

This is a direct fit oxygen sensor from NGK for your 2004 Nissan Frontier. Oxygen sensors are a key part of your vehicle's diagnostic system. They help keep your engine running at its best by monitoring the air-fuel ratio and sending that information back to the engine control unit. This helps maximize your fuel efficiency and reduce harmful emissions. A properly working sensor also alerts the onboard diagnostic system to potential issues 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 features a 3-stage coating that acts as a barrier against contaminants, protecting the sensor from poisoning and helping it last longer. They work closely with OEM manufacturers throughout the development process, ensuring their sensors meet the demands of modern engines.
