Please check notes in each part listing to ensure the Alternator is correct for your 1999 PORSCHE 911 with a 3.4L 3400cc engine. BBB PRECISION, REMY, ACDELCO, & BOSCH are competing brands, and each brand's Alternator may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Alternator fits only certain 1999 PORSCHE 911 models.
Clicking a "More Info" link will display a picture and/or other details about that Alternator in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Alternator, 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 Electrical parts, other PORSCHE 911 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 1999 PORSCHE will not be lost if you switch.
