⚖️ Seller Warranty & Marketplace Dispute Conciliation

Warranty claims should be made if, after correct installation and compatibility verification, the spark plugs exhibit a manufacturing defect, such as cracks in the ceramic insulator, sealing failure, or electrode defects not caused by misuse or adverse operating conditions. Issues arising immediately after installation that cannot be resolved with basic checks may indicate a manufacturing defect.
