Please check notes in each part listing to ensure the Oxygen (O2) Sensor Connector is correct for your 1996 CHEVROLET IMPALA with a 5.7L engine. ACDELCO, AIRTEX / WELLS, & STANDARD MOTOR PRODUCTS are competing brands, and each brand's Oxygen (O2) Sensor Connector may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Oxygen (O2) Sensor Connector fits only certain 1996 CHEVROLET IMPALA models.
Clicking a "More Info" link will display a picture and/or other details about that Oxygen (O2) Sensor Connector in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Oxygen (O2) Sensor Connector, 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 Electrical-Connector parts, other CHEVROLET IMPALA 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 1996 CHEVROLET will not be lost if you switch.
