Oxygen Sensor for BMW F20 F21 3/5/6/7 Series X3 X4 X5 Lambda Sensor

Keep your BMW running cleanly and efficiently with this O2 sensor replacement designed for a broad range of BMW models. Also known as a lambda sensor, this part monitors exhaust oxygen levels to help the engine maintain the optimal air-fuel ratio. By replacing a faulty sensor, you can restore consistent idle, improve fuel economy, and reduce emissions, all while helping your catalytic converter do its job more effectively. The sensor features magnetic induction sensing with a heating element for quick response across varying temperatures, ensuring reliable readings in both cold starts and cruising conditions.

Main Description

This BMW F20/F21 oxygen sensor is built to fit a wide spectrum of BMW vehicles, including 3, 5, 6, and 7 Series as well as X3, X4, and X5 lineups. It supports a range of OEM reference numbers to maximize compatibility and streamline replacement work for skilled technicians and DIY enthusiasts alike. The sensor is specified as a heating-type, magnetic-induction device, designed to provide fast, accurate oxygen readings to the engine management system. This translates to smoother throttle response, steadier idle, and better fuel efficiency by keeping the air-fuel mixture within optimal margins across driving conditions.

Key compatibility notes include fitment for BMW F20, F21, F22, F23, F87 variants and a variety of diesel and gasoline engines across the listed chassis. OEM numbers associated with this sensor include 13628589104, 13628572800, 13628593852, 8593852, 13628573760, 8573760, 8589104, 13628570689, 8570689, among others. Origin is Mainland China, and the part is manufactured to match the form, fit, and function of the original equipment while delivering dependable performance across a broad model range. All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.

For technicians and informed buyers, this sensor represents a practical, ready-to-install replacement that helps restore the vehicle’s emission control and fuel-management accuracy without needing extensive modifications. It’s designed to integrate with the BMW engine management system, ensuring the sensors’ readings are interpreted correctly and that the vehicle meets EU regulatory standards.

Benefits & Tips

• Restore precise air-fuel regulation to improve fuel economy and reduce exhaust emissions by maintaining optimal oxygen sensing in real-world driving.
• Enhance driveability with steadier idle and responsive acceleration once the sensor delivers accurate exhaust data again.
• Install by following standard replacement procedures for oxygen sensors—graceful removal of the old sensor and careful threading of the new one to avoid cross-thread damage. If you’re replacing a sensor that triggered diagnostic codes, consider clearing codes after installation to verify sensor health.
