Please check notes in each part listing to ensure the Cabin Air Filter is correct for your 2013 CADILLAC XTS with a 3.6L engine. PENTIUS, WIX, & ACDELCO are competing brands, and each brand's Cabin Air Filter may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Cabin Air Filter fits only certain 2013 CADILLAC XTS models.
Clicking a "More Info" link will display a picture and/or other details about that Cabin Air Filter in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Cabin 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 "Find More Parts" to find more Heat & Air Conditioning parts, other CADILLAC XTS 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 2013 CADILLAC will not be lost if you switch.
