NGK Infiniti I30 1999-1996 Direct Fit Oxygen Sensor

The ceramic element in this NGK oxygen sensor uses an advanced, 3-stage plasma jet and deposit trap overcoat. This design is key to protecting the sensor from contaminants that can poison it, helping to ensure it works correctly for longer. As a vital part of your vehicle's on-board diagnostic system, oxygen sensors like this one help the ECU maintain the optimal air-fuel ratio for good engine performance, better fuel efficiency, and reduced emissions.

NGK, a major supplier of original equipment oxygen sensors, builds these units with a focus on durability and performance. They work closely with vehicle manufacturers from the initial design stages through production, ensuring the sensor meets strict OE specifications. This direct-fit sensor is designed to replace your original part precisely, making installation straightforward.

When your oxygen sensor is working properly, it provides constant feedback to your car's computer, helping it run efficiently. If your check engine light is on, or you're noticing decreased fuel economy, replacing the oxygen sensor is often a necessary step to get your vehicle running right again.
