NGK Acura RLX 2017-2016 Direct Fit 5-Wire Wideband A/F Sensor

The advanced ceramic sensor element in this NGK wideband Air-Fuel Ratio sensor is built with a 3-stage contaminant-resistant plasma jet and deposit trap overcoat. This design helps protect the sensor element from poisoning, which is crucial for maintaining optimal engine performance and fuel efficiency.

As a critical part of your vehicle's on-board diagnostic system, this 5-wire wideband sensor produces a linear output signal. This allows your car's computer (ECU) to precisely determine how rich or lean the engine is running and make continuous adjustments to the air-fuel mixture. This keeps combustion as close to stoichiometric as possible, leading to better fuel economy and reduced emissions.

NTK, a leading OEM supplier, uses state-of-the-art technology to ensure complete control over the ceramics used in their sensors, from raw materials to the finished product. This direct-fit sensor is designed to integrate seamlessly with your 2016-2020 Acura RLX's existing system.
