Please check notes in each part listing to ensure the Air Temperature Sensor is correct for your 1998 CADILLAC CATERA with a 3.0L engine. DELPHI, STANDARD MOTOR PRODUCTS, & AIRTEX are competing brands, and each brand's Air Temperature Sensor may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Air Temperature Sensor fits only certain 1998 CADILLAC CATERA models.
Clicking a "More Info" link will display a picture and/or other details about that Air Temperature Sensor in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Air Temperature 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 CATERA 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 1998 CADILLAC will not be lost if you switch.
