Over time, the OEM ignition coils suffer from thermal breakdown due to prolonged heat soak within the engine bay, particularly on the rear bank located tightly against the firewall. This continuous thermal cycling degrades the internal epoxy potting and the primary and secondary copper windings. Simultaneously, factory spark plug gaps widen from normal electrode wear. Combined, these degradation factors lead to weak spark generation, resulting in partial combustion, idle misfires, sluggish throttle response, and a noticeable drop in fuel economy. Left unaddressed, unburned fuel can eventually damage the catalytic converters.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis comprehensive 6-pack of upgraded ignition coils and premium iridium spark plugs restores and enhances the secondary ignition circuit. The replacement coils feature advanced thermal epoxy and upgraded internal windings designed to resist heat soak and deliver a consistently higher voltage output. The included iridium spark plugs utilize an ultra-fine wire center electrode, requiring less firing voltage to bridge the gap while providing a substantially hotter, more concentrated spark. This optimal spark propagation ensures complete cylinder combustion, restoring factory torque curves, eliminating cold-start hesitations, and maximizing fuel burn efficiency across the entire RPM range. The matched components guarantee proper electrical resistance without triggering diagnostic trouble codes or a Check Engine Light (CEL).\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;\"\u003e2005-2017 Toyota Avalon\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;\"\u003e2GR-FE \/ GSX30, GSX40\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;\"\u003e268 hp \/ 248 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;\"\u003e673-1309, 23-0480, 23-0525, 52-1894, 52-2092, C1601SPEC, EBC1039, CUF487, EBC1214, EBC1832, 26C1034, 90919A2005, C1601VC, 5C1653, IGC0176, C1596VC\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e2005 Toyota Avalon 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2006 Toyota Avalon 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2007 Toyota Avalon 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2008 Toyota Avalon 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2009 Toyota Avalon 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2010 Toyota Avalon 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2011 Toyota Avalon 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2012 Toyota Avalon 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2013 Toyota Avalon 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2014 Toyota Avalon 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2015 Toyota Avalon 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2016 Toyota Avalon 3.5L V6\u003c\/li\u003e\n    \u003cli\u003e2017 Toyota Avalon 3.5L V6\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Toyota Reliability Standard\u003c\/h3\u003e\n  \u003cp\u003eEngineered for the demands of daily driving and long-term commuting, this matched ignition overhaul ensures your 2GR-FE maintains its smooth power delivery, maximized fuel economy, and renowned reliability.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48263137132792,"sku":"DS-EKGLZBK74","price":209.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-iridium-spark-plugs-for-toyota-avalon-2005-2017-3-5l-v6-1.jpg?v=1776746288","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-iridium-spark-plugs-for-toyota-avalon-2005-2017-3-5l-v6","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
