Please check notes in each part listing to ensure the Oil Pressure Switch is correct for your 1957 PLYMOUTH SUBURBAN with a 3.8L 230 engine. STANDARD MOTOR PRODUCTS & AIRTEX are competing brands, and each brand's Oil Pressure Switch may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Oil Pressure Switch fits only certain 1957 PLYMOUTH SUBURBAN models.

Clicking a "More Info" link will display a picture and/or other details about that Oil Pressure Switch in a separate window (you may need to turn off your pop-up-blocking software for this to work).

After choosing a Oil Pressure Switch, 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 Electrical-Switch & Relay parts, other PLYMOUTH SUBURBAN 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 1957 PLYMOUTH will not be lost if you switch.
