    Important<\/strong><\/p>\n

    Always check new spark plugs for transport damage before installation. Dented packaging may indicate that the ceramic insulator part has sustained a hairline crack. Damaged ceramic can come loose during use and cause serious engine damage.<\/p>\n

    Always check the prescribed electrode gap before installation. Even new spark plugs may have a deviating electrode gap during transport or storage. If necessary, carefully adjust the gap according to Mercedes factory specifications.<\/p>\n

    For optimal performance, we recommend always replacing spark plugs as a complete engine set. Simultaneously check the condition of the spark plug wires, distributor cap, and distributor rotor to prevent voltage loss and ignition malfunctions.<\/p>\n

    Always check before purchase and installation whether the part is suitable and equivalent based on photos, description, and specifications; installed or used parts cannot be returned.<\/p>","protected":false},"excerpt":{"rendered":"
