The ground electrode tip is also platinum combined with nickel-yttrium, providing consistent spark gap stability. This spark plug includes a 6000 ohm resistor to minimize radio frequency interference, ensuring smooth operation of vehicle electronics. Its flat seat design and 26.5 mm reach make it compatible with specific ignition systems requiring precise fitment. The pre-gap size of 0.8 mm is factory set to optimize ignition timing and combustion efficiency.\u003c\/p\u003e\u003ch2\u003eAbout the OE Fine Wire Double Platinum Product Line\u003c\/h2\u003e\u003cp\u003eThe OE Fine Wire Double Platinum line from Bosch is designed to meet original equipment specifications with enhanced electrode materials. This product line uses fine wire platinum electrodes on both the center and ground electrodes, which improves wear resistance and ignition reliability compared to conventional spark plugs. The double platinum design helps maintain a stable spark gap over time, reducing the need for frequent replacements and supporting consistent engine performance in vehicles like the Mercedes-Benz C-Class and Dodge models.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Common Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eMercedes-Benz C230, C250, C280, C300, C350\u003c\/li\u003e\n\u003cli\u003eMercedes-Benz CL550, CLK350, E280, E300, E350\u003c\/li\u003e\n\u003cli\u003eMercedes-Benz G550, GL550, GLK350, ML350, ML450, ML550\u003c\/li\u003e\n\u003cli\u003eMercedes-Benz R350, R550, S400, S450, S550, SL550, SLK280, SLK300, SLK350\u003c\/li\u003e\n\u003cli\u003eMercedes-Benz Sprinter 2500 and Sprinter 3500\u003c\/li\u003e\n\u003cli\u003eDodge models compatible with 4-cycle spark plugs requiring this specification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon Issues Addressed by Bosch YR7MPP33 Spark Plug\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEngine misfires due to worn or fouled spark plugs\u003c\/li\u003e\n\u003cli\u003eReduced fuel efficiency from inconsistent ignition\u003c\/li\u003e\n\u003cli\u003eDifficulty starting the engine in cold conditions\u003c\/li\u003e\n\u003cli\u003eRough idling or hesitation during acceleration\u003c\/li\u003e\n\u003cli\u003eInterference with vehicle electronics caused by spark plug noise\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the spark plug gap is set to the factory pre-gap of 0.8 mm before installation. Use a 16 mm socket wrench for proper torque application. Verify the flat seat type matches the engine’s cylinder head design to prevent compression leaks. Avoid over-tightening to protect the thread diameter of 12 mm and prevent damage. It is recommended to replace all spark plugs simultaneously to maintain balanced engine performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eBosch OE Fine Wire Double Platinum spark plugs are manufactured to meet strict OEM standards for fit, form, and function.
