Featuring a fine iridium tip and copper core electrodes, these plugs offer stable ignition and efficient combustion, which is critical for modern high-performance engines such as those found in Mercedes-Benz AMG and luxury models.\u003c\/p\u003e\u003ch2\u003eTechnical Details and Specifications\u003c\/h2\u003e\u003cp\u003eThis spark plug features a single ground electrode with a thin square tip, optimizing the spark path and reducing quenching effects. Both the center and ground electrodes use copper cores to enhance electrical conductivity, while the iridium tip on the center electrode ensures durability under high temperatures and pressures. The pre-gap size of 0.028 inches is factory set to meet precise ignition requirements. The flat seat design and 12 mm thread diameter ensure compatibility with specified Mercedes-Benz engines. The heat range of 8 is suitable for vehicles requiring a colder plug to prevent overheating during high-performance operation.\u003c\/p\u003e\u003ch2\u003eCompatible Mercedes-Benz Models\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eMercedes-Benz A35 AMG, A220, A250\u003c\/li\u003e\n\u003cli\u003eAMG GT series including AMG GT 55, 63, 63 S, Black Series, C, R, R Pro, and S\u003c\/li\u003e\n\u003cli\u003eC63 AMG, C63 AMG S, C300\u003c\/li\u003e\n\u003cli\u003eCLA35 AMG, CLA250\u003c\/li\u003e\n\u003cli\u003eE63 AMG S, E350\u003c\/li\u003e\n\u003cli\u003eG63 4x4 Squared AMG, G63 AMG, G550, G550 4x4\u003c\/li\u003e\n\u003cli\u003eGLA35 AMG, GLA250, GLB35 AMG, GLB250\u003c\/li\u003e\n\u003cli\u003eGLC63 AMG, GLC63 AMG S, GLC300\u003c\/li\u003e\n\u003cli\u003eGLE63 AMG S, GLE63 AMG S SUV, GLE350, GLE580\u003c\/li\u003e\n\u003cli\u003eGLS63 AMG, GLS580, Maybach GLS600, Maybach S560, Maybach S580\u003c\/li\u003e\n\u003cli\u003eS63 AMG, S63 AMG E Performance, S560, S580\u003c\/li\u003e\n\u003cli\u003eSL55 AMG, SL63 AMG, SL63 AMG S E Performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon Applications and Issues Addressed\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRestores consistent ignition in high-performance Mercedes-Benz engines\u003c\/li\u003e\n\u003cli\u003eImproves fuel efficiency by ensuring complete combustion\u003c\/li\u003e\n\u003cli\u003eReduces misfires and rough idling caused by worn spark plugs\u003c\/li\u003e\n\u003cli\u003eSupports engine responsiveness and acceleration\u003c\/li\u003e\n\u003cli\u003eHelps maintain emissions compliance by optimizing spark timing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the spark plug gap is checked before installation, although the pre-gap size of 0.028 inches is factory set.
