Please check notes in each part listing to ensure the Air Filter is correct for your 2004 CHEVROLET OPTRA with a 2.0L 1998cc engine. WIX, FRAM, & ACDELCO are competing brands, and each brand's Air Filter may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Air Filter fits only certain 2004 CHEVROLET OPTRA models.

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

After choosing a Air Filter, 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 CHEVROLET OPTRA 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 2004 CHEVROLET will not be lost if you switch.
