Please check notes in each part listing to ensure the Spark Plug is correct for your 1951 PLYMOUTH CONCORD with a 3.6L 218 engine. AUTOLITE, CHAMPION, & MOTORCRAFT are competing brands, and each brand's Spark Plug may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Spark Plug fits only certain 1951 PLYMOUTH CONCORD models.
Clicking a "More Info" link will display a picture and/or other details about that Spark Plug in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Spark Plug, 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 Ignition parts, other PLYMOUTH CONCORD 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 1951 PLYMOUTH will not be lost if you switch.
