The ground electrode tip combines platinum-iridium with nickel-yttrium and copper, enhancing longevity and consistent ignition. The tapered design of the ground electrode tip improves flame kernel growth and combustion efficiency. With a manufacturer heat range of 6 and a flat seat type, this spark plug is engineered to meet the specific thermal and mechanical requirements of Mercedes-Benz vehicles such as the C300, E350, CLS63 AMG, and G63 AMG.\u003c\/p\u003e\u003cp\u003eThe ceramic projected insulator ensures effective heat control and electrical insulation, while the resistor built into the plug reduces radio frequency interference, protecting sensitive vehicle electronics. The 14 mm hex size and 26.5 mm reach make installation straightforward for compatible engines. This spark plug is designed for 4-cycle engines and is supplied individually.\u003c\/p\u003e\u003ch2\u003eOE Fine Wire Double Iridium Product Line\u003c\/h2\u003e\u003cp\u003eThe Bosch OE Fine Wire Double Iridium line focuses on delivering precise ignition performance through the use of fine wire iridium electrodes on both the center and ground sides. This design reduces voltage requirements and improves ignitability, which can contribute to smoother engine operation and better fuel efficiency. The double iridium construction also enhances electrode durability, making these plugs suitable for high-performance and luxury vehicles like Mercedes-Benz models.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRestores consistent ignition in Mercedes-Benz C300, E350, CLS63 AMG, and other compatible models\u003c\/li\u003e\n\u003cli\u003eReduces misfires caused by electrode wear or fouling\u003c\/li\u003e\n\u003cli\u003eImproves fuel efficiency by ensuring optimal spark delivery\u003c\/li\u003e\n\u003cli\u003eMinimizes radio frequency interference affecting vehicle electronics\u003c\/li\u003e\n\u003cli\u003eSupports stable engine performance under various driving conditions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eVerify compatibility with your specific Mercedes-Benz model and engine type before installation\u003c\/li\u003e\n\u003cli\u003eUse a torque wrench to tighten the spark plug to manufacturer specifications to avoid damage\u003c\/li\u003e\n\u003cli\u003eCheck and adjust the pre-gap if necessary, though the plug comes pre-gapped at 0.7 mm\u003c\/li\u003e\n\u003cli\u003eInspect the spark plug hole for debris before installation to ensure proper seating\u003c\/li\u003e\n\u003cli\u003eReplace spark plugs in sets to maintain balanced engine performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eBosch OE Fine Wire Double Iridium spark plugs are manufactured to meet strict OEM standards, ensuring reliable performance and durability.
