Mounted directly above the valve cover in an enclosed compartment, this factory coil pack suffers severe thermal degradation. Over sustained thermal cycling, the internal epoxy potting cracks, causing dielectric breakdown and voltage arcing to the spark plug wells. Degraded boots and high internal winding resistance manifest as random misfires (DTC P0300 through P0304), rough cold-engine generator engagement, and unburned fuel entering the catalytic converter.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement ignition assembly is engineered with high-dielectric epoxy resin and reinforced secondary copper windings to resist insulation breakdown under heavy continuous electrical loads. Reinforced silicone plug boots provide a moisture-tight barrier against high-voltage flashover. Paired with fine-wire iridium spark plugs, this kit drastically reduces required firing voltages while maximizing flame kernel expansion. Laser-welded iridium center electrodes withstand arc erosion, ensuring consistent gap retention, lower primary coil amp draw, and complete fuel atomization during hybrid power generation.\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;\"\u003e2013-2015 Chevrolet Volt\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\u003eLUU\u003c\/strong\u003e 1.4L \/ \u003cstrong\u003eDelta II\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;\"\u003e84 hp \/ 93 lb-ft (Gas ICE)\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\u003e55577898\u003c\/strong\u003e, \u003cstrong\u003eUF669\u003c\/strong\u003e, \u003cstrong\u003e55579072\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\u003e2013 Chevrolet Volt Base Hatchback 1.4L L4 Electric\/Gas (LUU)\u003c\/li\u003e\n  \u003cli\u003e2014 Chevrolet Volt Base Hatchback 1.4L L4 Electric\/Gas (LUU)\u003c\/li\u003e\n  \u003cli\u003e2015 Chevrolet Volt Base Hatchback 1.4L L4 Electric\/Gas (LUU)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the Delta II Volt?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2013-2015 Chevrolet Volt equipped with the \u003cstrong\u003eLUU\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre the iridium spark plugs pre-gapped for the 1.4L engine?\u003c\/strong\u003e\u003cbr\u003e Yes, the spark plugs are pre-set to factory specifications, though verifying gap clearance before installation is always standard practice.\u003c\/p\u003e\n\n\u003ch3\u003eThe Chevrolet Hybrid Efficiency Caliber\u003c\/h3\u003e\n\u003cp\u003eMaintaining precise ignition voltage in extended-range hybrid powertrains is critical for emissions compliance and seamless internal combustion engine engagement during high-load battery recharge cycles.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50594399486200,"sku":"DS-EHCAUO1VZ","price":64.95,"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-chevrolet-volt-2013-2015-1-4l-1.jpg?v=1790058840","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-chevrolet-volt-2013-2015-1-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
