Please check notes in each part listing to ensure the Mass Air Flow Sensor is correct for your 2006 CADILLAC STS with a 3.6L engine. ACDELCO, A-1 CARDONE, & AIRTEX are competing brands, and each brand's Mass Air Flow Sensor may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Mass Air Flow Sensor fits only certain 2006 CADILLAC STS models.
Clicking a "More Info" link will display a picture and/or other details about that Mass Air Flow Sensor in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Mass Air Flow Sensor, 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 Emission parts, other CADILLAC STS 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 2006 CADILLAC will not be lost if you switch.
