Upstream Downstream O2 Sensor Set for Infiniti QX56 QX80 | Complete oxygen sensor replacement set for Infiniti QX56 and QX80. Stable Lambda Signal($58.67Value)
Direct OE Match Design - Engineered to meet original equipment specifications for INFINITI QX56 2011-2013,for INFINITI QX80 2014, and other select models with matching engine code. This O2 sensor delivers reliable operation and confirmed electrical compatibility when the provided OE reference number matches your original part. Advanced Zirconia Sensing Element - Utilizes a high-sensitivity dual-layer ceramic element capable of detecting oxygen fluctuations in the tailpipe stream within milliseconds. This lambda sensor rapid feedback loop enables the engine computer to optimize fuel injection instantly, a critical factor in maintaining combustion efficiency and meeting required standards. Extreme Thermal & Vibration Durability - Engineered for lasting O2 sensor performance, this oxygen sensor features a PTFE-insulated wire harness and a rugged stainless steel external shield. This lambda sensor construction effectively blocks intense under-hood heat, resists tailpipe corrosion, and minimizes the risk of premature failure caused by severe thermal cycling and vibration. Assists in Optimizing Engine Function - A sluggish oxygen sensor distorts essential engine data. Our high-precision model supports accurate monitoring by the engine control unit, which can assist in restoring engine harmony, smoothing out rough idling, and bringing fuel consumption back to its normal range. Vital Pre-Purchase Checklist - Confirm your vehicle's Year, Make, Model, Engine, and sensor location (Upstream vs. Downstream) before ordering. Match the OE number on your original sensor to our listing. Use the "Amazon Confirmed Fit" bar; always hover over the blue "i" for additional fitment notes.
