Please check notes in each part listing to ensure the Voltage Regulator is correct for your 1999 BMW 328I with a 2.8L engine. Special restrictions like "California only" or "with sport package" may indicate a Voltage Regulator fits only certain 1999 BMW 328I models.
Clicking a "More Info" link will display a picture and/or other details about that Voltage Regulator in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Voltage Regulator, 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 "Find More Parts" to find more Electrical parts, other BMW 328I parts or parts for a different vehicle. Please try our Interactive Catalog (click link above) for faster searching. Both catalogs use the same shopping cart so any auto parts you've already chosen for your 1999 BMW will not be lost if you switch.
