Condition:

Please note this spark plug is missing the lower electrode/firing end and is incomplete. It is being sold exactly the way I found it. The porcelain remains in excellent condition, while the metal components show age, oxidation, and surface wear consistent with long-term storage. Please review all photos carefully for condition and measurements.

Found in recent barns, storage units, estates, and anywhere rusty gold hides. Please see all of the photos for condition and measurements. I will combine shipping on multiple orders, so be sure to check out my other items. If you have any questions, please let me know. Thank you.
