Oxygen Sensor Upstream Air Fuel Ratio Lambda for Hyundai Santa Fe

Upgrade your Hyundai Santa Fe’s emissions management with this Oxygen Sensor Upstream Air Fuel Ratio Lambda, designed for 2.7L engines and calibrated for a precise upstream O2 reading. Built to match OEM specifications, this sensor helps the engine control unit (ECU) optimize fuel mixture in real time, delivering smoother idling, improved throttle response, and cleaner exhaust. Whether you’re maintaining an older Santa Fe or restoring peak efficiency, this upstream sensor ensures accurate feedback from the exhaust stream, minimizing unnecessary fuel consumption and reducing emission levels.

Engineered for compatibility with Hyundai Santa Fe, Kia Magentis, Kia Optima, and Kia Rondo models with a 2.7L engine, this sensor aligns with the upstream right position and uses a heating-type design for fast response, even in cold starts. Its piezoelectric sensing element provides reliable, fast-reacting readings across a broad range of operating conditions, helping your vehicle meet emission standards and pass inspections.
