Over time, factory coil housings suffer dielectric breakdown and micro-cracking along the boots, leading to secondary voltage leakage and rough idling. Concurrently, factory plug electrodes erode, widening the gap and overworking the coils, which frequently causes ignition hesitation, DME misfire fault codes, and sluggish throttle response under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement kit resolves ignition voltage drops by utilizing premium primary and secondary copper windings wrapped in heat-resistant epoxy housings. These direct-fit coil assemblies deliver stable high-voltage output across all engine speeds. Paired with fine-wire iridium spark plugs that resist electrode erosion and fouling, this kit maintains optimal spark gap integrity, ensures crisp throttle response, and prevents spark blowout under peak boost.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2012-2018 BMW 6 Series (640i \/ 640i xDrive)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e3.0L Turbo I6 (N55B30) \/ F06, F12, F13\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e315 hp \/ 330 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eUF515, UF-515, UF522, UF-522\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2012-2018 BMW 640i Base Coupe \/ Convertible 3.0L L6 (F12 \/ F13)\u003c\/li\u003e\n  \u003cli\u003e2013-2018 BMW 640i Gran Coupe 3.0L L6 (F06)\u003c\/li\u003e\n  \u003cli\u003e2014-2018 BMW 640i xDrive Coupe \/ Convertible 3.0L L6 (F12 \/ F13)\u003c\/li\u003e\n  \u003cli\u003e2014-2018 BMW 640i xDrive Gran Coupe 3.0L L6 (F06)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe BMW Precision Standard\u003c\/h3\u003e\n\u003cp\u003eCalibrated specifically for European engine management protocols, these components match factory dwell times and resistance parameters to ensure seamless DME integration and zero check-engine light triggers.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50451971637496,"sku":"DS-E5NDGMDR8","price":101.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-and-iridium-spark-plugs-for-bmw-6-series-2012-2018-3-0l-1.jpg?v=1788715294","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-and-iridium-spark-plugs-for-bmw-6-series-2012-2018-3-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
