Please check notes in each part listing to ensure the Oxygen Sensor is correct for your 1994 BMW M3 with a 3.0L 2990cc [S50] engine. QUINTON HAZELL & BOSCH are competing brands, and each brand's Oxygen Sensor may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Oxygen Sensor fits only certain 1994 BMW M3 models.

Clicking a "More Info" link will display a picture and/or other details about that Oxygen Sensor in a separate window (you may need to turn off your pop-up-blocking software for this to work).

After choosing a Oxygen Sensor, click the "Add Part" button. Shipping costs will be shown on the Shopping Cart page. You may use your browser's Back button, or click on "Find More Parts", to find more Emission parts, other BMW M3 parts, or parts for a different vehicle. Please try our Interactive Catalog (click red Start button above) for faster searching. Both catalogs use the same shopping cart, so any auto parts you've already chosen for your 1994 BMW will not be lost if you switch.
