As the 2.2L and 2.4L engines cycle through thousands of heat variations, the OEM coil packs suffer from internal coil winding breakdown and epoxy housing micro-fractures. This leads to voltage leaks, increased electrical resistance, and weak spark delivery under load. Simultaneously, standard copper or worn platinum spark plugs widen their gap due to electrode erosion, forcing the aging coils to work harder, ultimately resulting in erratic idling, hesitation during acceleration, and decreased fuel economy.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis ignition and spark plug kit addresses these thermal and electrical vulnerabilities directly. The upgraded ignition coils feature high-grade silicone boots to resist heat soak and prevent arcing, alongside premium copper wire windings that ensure a consistent, high-voltage energy transfer to the plug. Paired with performance iridium spark plugs, the system benefits from an ultra-fine center electrode. Iridium's exceptional melting point and structural hardness allow for a precise, concentrated spark that prevents blowout under high cylinder pressures. This translates to a more complete fuel burn, instantly restoring lost horsepower, stabilizing torque delivery, and providing a smoother idle.\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;\"\u003e2007-2012 Chevrolet Malibu\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;\"\u003eEcotec L61, LE5 \/ GM Epsilon Platform\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;\"\u003e144-170 hp \/ 155-160 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;\"\u003eUF491 \/ 41-103\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2007-2012 Chevrolet Malibu 2.2L I4\u003c\/li\u003e\n  \u003cli\u003e2007-2012 Chevrolet Malibu 2.4L I4\u003c\/li\u003e\n  \u003cli\u003eInterchange Part Numbers (Coils): UF491, 12578224, 12578244, 12589623, 12629646, C1552, C1552-4, C1809, GN10485, IC571, D516C, 5C1609, C-706, 26C1039, IGC4059HU, 921-2090, SKIC165, CUF491, V40-70-0084, 48973\u003c\/li\u003e\n  \u003cli\u003eInterchange Part Numbers (Plugs): 41-103, 12638824, 673-7201\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Chevrolet Calibration\u003c\/h3\u003e\n\u003cp\u003eDesigned for daily-driven and high-mileage Ecotec powerplants, this setup ensures OEM-tier reliability with enhanced throttle response, providing consistent power delivery and a misfire-free drive cycle.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48263068319992,"sku":"DS-EUID369HD","price":149.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-iridium-spark-plugs-for-chevrolet-malibu-2007-2012-2-2l-2-4l-i4-1.jpg?v=1776744195","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-iridium-spark-plugs-for-chevrolet-malibu-2007-2012-2-2l-2-4l-i4","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
