BMW Oxygen Sensor - O2 Sensors for BMW Z3 (1996-2002)

Clear BMW chassis

Please ensure your correct model is selected

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.

Upgrade Your Engine with an Efficient O2 Sensor Replacement

If your engine is triggering an oxygen sensor check engine light, it's time to consider a replacement with this high-performance unit. The O2 sensor is a critical component that measures unburned fuel in the exhaust pipe, enabling precise fuel mapping adjustments for reduced emissions and improved fuel economy.

When the O2 sensor malfunctions, your vehicle's MPG and overall performance can suffer. The good news is that replacing this unit is a straightforward process that can quickly restore your engine's performance and mileage. To ensure easy removal in the future, apply some anti-seize on the threads.

Regular, scheduled maintenance should include the O2 sensor replacement, as these sensors have a tendency to degrade slowly over time.
