Please check notes in each part listing to ensure the Tensioner Pulley is correct for your 2003 BMW 320I with a 2.2L 2171cc 132 [M54] engine. GATES & ACDELCO are competing brands, and each brand's Tensioner Pulley may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Tensioner Pulley fits only certain 2003 BMW 320I models.
Clicking a "More Info" link will display a picture and/or other details about that Tensioner Pulley in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Tensioner Pulley, 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 Belt Drive parts, other BMW 320I 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 2003 BMW will not be lost if you switch.
