BMW Oxygen Sensor - O2 Sensors

If your BMW's Check Engine light is illuminated and displaying error codes, this Oxygen sensor might hold the solution. Tailored for your MINI, this sensor monitors the fuel-air mixture, providing essential data to the ECU for optimizing performance. Featuring a heated design, it's specifically crafted for the pre-catalytic converter.

Keep a close watch on significant drops in gas mileage, as this may indicate the need for O2 sensor replacement. Also referred to as a Lambda Probe, this sensor plays a pivotal role in ensuring the efficiency of your BMW's engine.

The oxygen sensor is part of your BMW's emissions control system and feeds data to BMW engine management computer. The oxygen sensor is positioned in the exhaust pipe and can detect rich and lean mixtures. The goal of the oxygen sensor is to help the engine run as efficiently as possible and also to produce as few emissions as possible. When your BMW oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing -- resulting in poor performance, poor gas mileage, and increased pollution. Make sure your BMW engine performs as it should, and doesn't use more fuel than it needs to, by simply changing your oxygen sensor today.

This item fits the following BMW Chassis:
E82,E90,E92,E93,F30,F34

Fits BMW Engines including:

BMW B58 3.0L Oxygen Sensor - Downstream is essential for maintaining optimal engine performance and fuel efficiency. Turner Motorsport offers this high-quality replacement sensor designed to precisely measure exhaust oxygen levels, allowing the vehicle's computer to accurately adjust the air/fuel ratio and monitor emissions. A degraded oxygen sensor can lead to decreased engine performance, reduced fuel efficiency, and increased harmful emissions, potentially triggering the Check Engine Light and causing a failure in emissions testing.

• Ensures Optimal Engine Performance: Accurately measures exhaust oxygen levels for precise air/fuel ratio adjustments.
• Improves Fuel Efficiency: Helps maintain proper fuel mixture, reducing fuel consumption.
• Reduces Harmful Emissions: Keeps emissions in check, ensuring compliance with environmental standards.
• Prevents Check Engine Light Activation: Helps avoid unnecessary warning lights and potential emissions test failures.
• Quality Replacement: High-grade sensor designed specifically for the BMW B58 3.0L engine.

A new oxygen sensor can improve driveability and lengthen engine life. Ultimately, you achieve a smoother running engine that is more fuel efficient. Feedback from the oxygen sensor provides closed-loop control of the injected quantity of fuel for optimum air-fuel mixture, enabling virtually complete combustion to take place. Contaminants in gas and certain atmospheric conditions can drastically shorten the life of any oxygen sensor, therefore they should be checked with every periodic maintenance and changed if necessary.

This is the OEM Bosch oxygen sensor for 325i and 325Ci E46 BMW's. This sensor is mounted in the manifold before the catalytic converter. OEM replacement for BMW # 11787515826.
