Please check notes in each part listing to ensure the Fuel Injector is correct for your 2003 PORSCHE CAYENNE S with a 4.5L 4511cc engine. Special restrictions like "California only" or "with sport package" may indicate a Fuel Injector fits only certain 2003 PORSCHE CAYENNE S models.

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

After choosing a Fuel Injector, 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 Fuel/Air parts, other PORSCHE CAYENNE S 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 PORSCHE will not be lost if you switch.
