Over time, internal winding resistance increases and the protective epoxy micro-cracks, causing voltage leaks. Standard spark plugs also suffer from rapid electrode wear, which inherently widens the spark gap. This higher voltage demand stresses aging coils, causing spark blow-out under load, rough idling, incomplete fuel atomization, and lost torque.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis ignition upgrade resolves these issues using high-grade internal components. The replacement coils feature high-density copper windings and high-dielectric epoxy to resist thermal breakdown and deliver maximum voltage output. Paired with fine-wire iridium spark plugs, the system requires less electrical energy to bridge the gap while generating a hotter, more consistent flame kernel. Iridium’s ultra-high melting point prevents gap widening over the life of the plug. This synergy ensures optimal cylinder pressure, precise spark timing, and restores factory horsepower, throttle response, and fuel efficiency.\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;\"\u003e2011-2016 Scion tC\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;\"\u003e2AR-FE \/ AGT20\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;\"\u003e180 hp \/ 173 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Numbers\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e673-1309, 23-0480, 23-0525, 52-1894, 52-2092, EBC1039, 90919A2005, 5C1653\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e2011 Scion tC 2.5L I4\u003c\/li\u003e\n    \u003cli\u003e2012 Scion tC 2.5L I4\u003c\/li\u003e\n    \u003cli\u003e2013 Scion tC 2.5L I4\u003c\/li\u003e\n    \u003cli\u003e2014 Scion tC 2.5L I4\u003c\/li\u003e\n    \u003cli\u003e2015 Scion tC 2.5L I4\u003c\/li\u003e\n    \u003cli\u003e2016 Scion tC 2.5L I4\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Scion Performance Standard\u003c\/h3\u003e\n  \u003cp\u003eEngineered to meet the electrical demands of modern JDM platforms, this ignition overhaul ensures the 2AR-FE delivers reliable, consistent power delivery whether navigating daily commutes or pushing through spirited canyon roads.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48266402103544,"sku":"DS-EK2BNUYPL","price":144.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-iridium-spark-plugs-for-scion-tc-2011-2016-2-5l-i4-1.jpg?v=1776814509","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-iridium-spark-plugs-for-scion-tc-2011-2016-2-5l-i4","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
