Over time, heat soak degrades the internal epoxy resin and insulation around the primary and secondary copper windings. This leads to internal resistance spikes, micro-arcing, and high-rpm misfires under boost. Compounding this, standard spark plugs erode at the ground electrode, expanding the plug gap and forcing the coil to pull excessive current, triggering driveability faults and CEL codes such as P0300 through P0304.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive kit provides 4 matched coil-on-plug assemblies engineered with high-conductivity copper windings and heat-resistant elastomer boots that prevent dielectric breakdown. Paired with 4 laser-welded iridium spark plugs, the setup ensures a concentrated, stable spark kernel even under peak boost pressures. The fine-wire iridium center electrode resists thermal ablation and carbon fouling, maintaining precise gap tolerance and smooth combustion across the entire RPM range.\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 3 Series\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;\"\u003e2.0L Turbo (N20 \/ N26) \/ F30, F31, F34\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;\"\u003e180–240 hp \/ 200–255 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;\"\u003eUF667, UF-667\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 3 Series (320i, 320i xDrive, 328i, 328i xDrive) 2.0L Turbo 4-Cylinder\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe BMW Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet tight European OBD-II communication and resistance tolerances, this direct-fit ignition kit ensures zero misfire-induced limp mode activations, instantaneous cold starts, and seamless power delivery.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50458918093048,"sku":"DS-ESN75CZKB","price":111.95,"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-3-series-2012-2018-2-0l-1.jpg?v=1788803484","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-bmw-3-series-2012-2018-2-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
