Concurrently, factory spark plugs suffer from electrode erosion and gap widening, placing increased electrical resistance on aging internal coil windings. This degradation leads to weak spark output, unburned fuel entering the exhaust tract, rough cold starts, and intermittent P0300–P0304 diagnostic trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete ignition kit features four heavy-duty ignition coils paired with fine-wire iridium spark plugs. The coils utilize high-grade internal copper windings and specialized epoxy potting to resist thermal breakdown and provide consistent kilovolt output under high load. The matched iridium plugs provide superior thermal conductivity and a minimal electrode surface area, lowering the required ionization voltage while offering extreme resistance to spark erosion and carbon fouling.\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;\"\u003e2009-2017 Mitsubishi Lancer 2.4L\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;\"\u003e4B12 MIVEC \/ CY5A\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;\"\u003e168 hp \/ 167 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number \/ OEM Cross-Reference\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eUF589, 1832A016, FK0320, 5C1751, C1694, GN10519\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2009-2017 Mitsubishi Lancer GTS (2.4L L4 4B12)\u003c\/li\u003e\n  \u003cli\u003e2011-2017 Mitsubishi Lancer SE \/ SEL (2.4L L4 4B12)\u003c\/li\u003e\n  \u003cli\u003e2010-2011 Mitsubishi Lancer Sportback GTS (2.4L L4 4B12)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Mitsubishi JDM Performance Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to withstand aggressive cam profiles and continuous MIVEC variable valve operation, this kit delivers sharp throttle response and complete fuel combustion across the entire rev band.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50429903536376,"sku":"DS-EL35D8A5C","price":109.95,"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-mitsubishi-lancer-2009-2017-2-4l-1.jpg?v=1788452740","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-mitsubishi-lancer-2009-2017-2-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
