Over time, OEM coil epoxy breaks down, resulting in dielectric breakdown, internal arc tracking, and primary winding resistance drift. Simultaneously, standard spark plug electrodes erode, widening the gap under boost and causing spark blowout, rough idle, DME misfire fault codes (such as 29CD-29D2), and limp-mode triggers under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive kit features six direct-fit coil-on-plug assemblies engineered with high-purity internal copper windings, heavy-gauge magnetic laminations, and premium thermoset epoxy housings to prevent dielectric flashover under thermal stress. Paired with six fine-wire iridium spark plugs, the kit ensures ultra-low ionization resistance, higher spark kernel energy, and exceptional erosion resistance under high cylinder pressures.\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;\"\u003e2012-2016 BMW Z4\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;\"\u003eN54B30 \/ E89\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;\"\u003e300 hp \/ 300 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\u003e2012-2016 BMW Z4 sDrive35i (3.0L Inline-6 Turbo, E89)\u003c\/li\u003e\n  \u003cli\u003e2012-2016 BMW Z4 sDrive35is (3.0L Inline-6 Turbo, E89)\u003c\/li\u003e\n  \u003cli\u003e2012-2016 BMW Z4 3.0L Inline-6 Cyl Models\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe BMW Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to exact Bavarian tolerances, these direct-replacement ignition components interface seamlessly with the Bosch\/Siemens DME without triggering false misfire codes or check engine lights, ensuring factory cold-start reliability and smooth high-RPM power delivery.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50451963412728,"sku":"DS-EJ3Z9VAY5","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-z4-2012-2016-3-0l-1.jpg?v=1788714823","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-and-iridium-spark-plugs-for-bmw-z4-2012-2016-3-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
