Over time, OEM coil pack epoxy insulation degrades, causing dielectric breakdown, micro-arcing, and spark blowout under peak boost. Concurrently, factory spark plug gaps erode, increasing electrical resistance, stressing the ignition drivers, and inducing rough idle or high-RPM hesitation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement ignition service kit features six heavy-duty coil-on-plug assemblies engineered with high-purity internal copper windings and thermal-resistant resin housings. Paired with six fine-wire iridium spark plugs, this kit provides a concentrated, high-energy spark kernel with superior thermal dissipation. The iridium center electrode resists electrical erosion under extreme cylinder pressures, ensuring stable combustion, crisp throttle response, and extended service intervals.\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;\"\u003e2015-2018 BMW M3\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;\"\u003eS55B30 \/ F80\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;\"\u003e425 hp \/ 406 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\u003e2015 BMW M3 Base Sedan 3.0L L6 Twin-Turbo (S55B30)\u003c\/li\u003e\n  \u003cli\u003e2016 BMW M3 Base Sedan 3.0L L6 Twin-Turbo (S55B30)\u003c\/li\u003e\n  \u003cli\u003e2017 BMW M3 Base \/ Competition Sedan 3.0L L6 Twin-Turbo (S55B30)\u003c\/li\u003e\n  \u003cli\u003e2018 BMW M3 Base \/ Competition \/ CS Sedan 3.0L L6 Twin-Turbo (S55B30)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe BMW Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to exact OEM operational tolerances, this kit maintains clean DME communication without triggering false misfire codes or check engine lights, delivering reliable spark delivery under demanding street and track driving conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50451974062328,"sku":"DS-EMV72J7DM","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-m3-2015-2018-3-0l-1.jpg?v=1788715679","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-bmw-m3-2015-2018-3-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
