NGK Infiniti I30 2001-2000 Direct Fit Oxygen Sensor

This NGK oxygen sensor is a direct fit for your 1998-2001 Nissan Maxima or 1999-2001 Infiniti I30. Oxygen sensors are a key part of your vehicle's diagnostic system, working to keep the engine running smoothly, get the best possible gas mileage, and cut down on exhaust emissions. It constantly sends information to your car's computer about the air-fuel mix, helping it make adjustments and also alerting you if there's an issue with fuel delivery or the catalytic converter.

NGK, known as NTK in the OEM world, is a major supplier of these critical components. They use advanced ceramic technology, controlling the sensor element from the raw materials all the way to the finished product. This particular sensor features a 3-stage contaminant-resistant plasma jet and deposit trap overcoat. This design helps protect the sensor element from poisoning by contaminants, which can lead to premature failure.
