NGK Infiniti G20 1999 Direct Fit Oxygen Sensor

This NGK oxygen sensor is what you get when you need to replace the one on your 1996-1999 Infiniti I30, 1999 Infiniti G20, 1998 Nissan 200SX, or 1997-1999 Nissan Maxima. As a vital part of your vehicle's diagnostic system, the oxygen sensor constantly sends information to the engine control unit (ECU) about the air-fuel mixture. This feedback is crucial for keeping your engine running smoothly, getting the best possible gas mileage, and reducing harmful exhaust emissions.

NGK, a major supplier of original equipment oxygen sensors, builds these with an advanced ceramic sensor element. This element features a three-stage protective coating that acts as a plasma jet and deposit trap. This design helps shield the sensor from contaminants that could otherwise poison it, leading to premature failure. Because NTK is a ceramics company at its core, they have a lot of control over the quality of the ceramic element, from the raw materials all the way to the finished product.
