Continuous thermal cycling and engine bay heat soak degrade the internal epoxy resin and primary\/secondary windings over time. This breakdown causes dielectric breakdown, micro-arcing inside the spark plug boots, and high-rpm secondary resistance spikes.

The integrated silicone spark plug boots feature heat-resistant internal resistors to reject voltage leak to ground under high thermal load. Paired with four matched OE-spec spark plugs calibrated to factory heat range and gap, this kit ensures complete combustion chamber flame propagation, reduced electrical load on the primary driver circuit, and instant cold-start ignition.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100% style=\" border-collapse: collapse border: solid font-size: min-width:\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;\"\u003e2013-2017 Chevrolet Sonic\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;\"\u003e1.8L LUW\/LWE Ecotec \/ Gamma II T300\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;\"\u003e138 hp \/ 125 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;\"\u003eUF620, 25186687, 55561655, 96476983, C1646, D517C\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2013 Chevrolet Sonic LS, LT, LTZ 1.8L L4 Gas \/ Flex (LUW \/ LWE)\u003c\/li\u003e\n  \u003cli\u003e2014 Chevrolet Sonic LS, LT, LTZ 1.8L L4 Gas \/ Flex (LUW \/ LWE)\u003c\/li\u003e\n  \u003cli\u003e2015 Chevrolet Sonic LS, LT 1.8L L4 Gas \/ Flex (LUW \/ LWE)\u003c\/li\u003e\n  \u003cli\u003e2016 Chevrolet Sonic LS, LT 1.8L L4 Gas \/ Flex (LUW \/ LWE)\u003c\/li\u003e\n  \u003cli\u003e2017 Chevrolet Sonic LS, LT 1.8L L4 Gas \/ Flex (LUW \/ LWE)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the T300 Sonic?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2013-2017 Chevrolet Sonic equipped with the 1.8L LUW\/LWE engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need to gap the spark plugs prior to installation?\u003c\/strong\u003e\u003cbr\u003e While pre-gapped, always verify plug gap with a feeler gauge to the factory 0.028\" specification before final torquing.\u003c\/p\u003e\n\n\u003ch3\u003eThe Chevrolet Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for daily urban commuter abuse and long-distance duty cycles, this ignition package delivers steady voltage delivery and clean combustion to keep your GM powertrain operating within factory emissions and fuel-economy targets.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50625923154168,"sku":"DS-EC1WZC8DA","price":127.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-spark-plugs-for-chevrolet-sonic-2013-2017-1-8l-1.jpg?v=1790352936","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-spark-plugs-for-chevrolet-sonic-2013-2017-1-8l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
