BMW Oxygen Sensor - O2 Sensors

Every new BMW, and all BMW cars made from 1980 on, have an oxygen sensor, often called an "O2 sensor". 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. We carry Bosch oxygen sensors, and in some cases Genuine BMW oxygen sensors or OEM oxygen sensors.

If your engine is tossing you an oxygen sensor check engine light, replace it with this unit from Bosch. The O2 sensor measures the amount of unburned fuel in the exhaust pipe to adjust fuel mapping for less emissions and better fuel economy. When malfunctioning, your MPG and performance can suffer. Replaced fairly easily, you can restore your performance and mileage quickly. Put some anti seize on the threads to prevent it from becoming a permanent part of the exhaust. Regularly scheduled maintenance as these tend to fail slowly.

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.

Oxygen sensors measure exhaust oxygen. Their signals are used by the vehicle computer to adjust the air/fuel ratio and test vehicle emissions. Degraded oxygen sensors reduce engine performance and fuel efficiency, and increase harmful tailpipe emissions. They can also turn on the Check Engine Light and cause a car to fail an emissions test.

The oxygen sensor is vital to the performance and drivability of your car. The engine computer relies on data from the sensor to make adjustments in engine efficiency and performance. 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. There is no lifespan on O2 sensors but there are several fault codes that indicate a failed sensor (O2 monitoring, cat efficiency, O2 heating circuit, O2 readiness, and others). The O2 sensor is heated and has a self-calibration feature so once you get the codes or feel performance has suffered, a new sensor is a good starting point to get you back to peak performance. Febi's Oxygen sensors are high quality and will give you the longest and best performance for the price.
