Engine bay heat soak degrades the internal epoxy potting of the factory coils, resulting in dielectric breakdown, high-voltage leakage, and unburned hydrocarbon accumulation. Combined with eroded spark plug ground electrodes over extended service cycles, this ignition degradation causes erratic idle, hesitation under load, poor fuel economy, and persistent \u003cstrong\u003eP0300\u003c\/strong\u003e through \u003cstrong\u003eP0306\u003c\/strong\u003e diagnostic trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis service kit features high-temperature dielectric boots and reinforced primary and secondary copper windings designed to resist internal insulation breakdown. Matched with pre-gapped, thermally stable spark plugs, this kit guarantees consistent arc generation and stable flame propagation under load. Replacing both the coil packs and plugs concurrently restores factory dwell timing, optimizes flame kernel development inside the combustion chamber, and preserves catalytic converter health.\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; margin-bottom: 20px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2010-2011 Jeep Liberty\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003e3.7L PowerTech V6 (EKG)\u003c\/strong\u003e \/ \u003cstrong\u003eKK\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e210 hp \/ 235 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003e5149199AA\u003c\/strong\u003e, \u003cstrong\u003e68320417AA\u003c\/strong\u003e, \u003cstrong\u003eUF640\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2010 Jeep Liberty 3.7L V6 (Sport, Limited, Renegade)\u003c\/li\u003e\n  \u003cli\u003e2011 Jeep Liberty 3.7L V6 (Sport, Limited, Renegade)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the KK Liberty?\u003c\/strong\u003e\u003cbr\u003e Yes, this kit is engineered as a direct replacement for the 2010-2011 Jeep Liberty \u003cstrong\u003eKK\u003c\/strong\u003e equipped with the \u003cstrong\u003e3.7L PowerTech V6\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy are there only 3 coils for a 6-cylinder engine?\u003c\/strong\u003e\u003cbr\u003e This engine utilizes a waste-spark ignition configuration where three dual-tower coils mount on one cylinder bank and supply high-voltage secondary current to the opposite cylinders via plug wires.\u003c\/p\u003e\n\n\u003ch3\u003eThe Jeep Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for high-vibration off-road duty and continuous low-speed crawling, these ignition components resist severe thermal cycling to maintain dependable ignition delivery under heavy trail loads and utility towing.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50623709577464,"sku":"DS-E2OYP0JG8","price":97.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-spark-plugs-for-jeep-liberty-2010-2011-3-7l-1.jpg?v=1790298526","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-spark-plugs-for-jeep-liberty-2010-2011-3-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
