Please check notes in each part listing to ensure the Air Filter is correct for your 1975 CHEVROLET EL CAMINO CUSTOM with a 7.4L 454 4BBL engine. AUTO EXTRA, PRO-TEC, & WIX 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 1975 CHEVROLET EL CAMINO CUSTOM 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 EL CAMINO CUSTOM 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 1975 CHEVROLET will not be lost if you switch.
