NGK Lexus LS400 1992-1990 Direct Fit Oxygen Sensor

NGK is known worldwide as the largest supplier and manufacturer of original equipment oxygen sensors. For your 1990-1992 Lexus LS400, this direct fit oxygen sensor is a crucial part of your vehicle's on-board diagnostic system. It works to keep your engine running at its best, maximizing how far you get on a tank of gas and helping to keep harmful emissions in check. By providing constant feedback to your car's computer, it helps manage the air-fuel mixture and alerts you to potential issues with fuel delivery or the catalytic converter.

At its heart, NTK is a ceramics company, and they use advanced technology to control the ceramic element in their oxygen sensors from the very beginning. This means they have a unique ability to manage the quality of the sensor's core component. The advanced ceramic sensor element features a 3-stage plasma jet and deposit trap overcoat that resists contamination, protecting the element from poisoning and ensuring consistent performance over time. NTK works closely with OEM manufacturers through every step of development, from the initial idea to the final production, to continually improve sensor designs and enhance resistance to failure.
