Over time, high cylinder head temperatures compromise internal epoxy potting, while standard spark plug gaps erode, elevating secondary voltage demand. This causes weak spark delivery, sluggish throttle response, reduced fuel economy, and intermittent DTC misfire codes under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete ignition kit features four heavy-duty direct-replacement pencil coils engineered with high-dielectric resin and premium copper windings to deliver consistent peak voltage discharge. Paired with four ILZKAR8H8S-specification iridium spark plugs featuring laser-welded fine-wire center electrodes, this set reduces required ignition voltage, prevents quench, and provides exceptional resistance to spark erosion and high-heat fouling.\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;\"\u003e2016-2021 Honda Civic (2.0L Naturally Aspirated)\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;\"\u003eK20C2 \/ FC2 (Sedan), FC4 (Coupe)\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;\"\u003e158 hp \/ 138 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;\"\u003eUF749, UF-749, 30520-5R0-013, 30520-5R0-003, ILZKAR8H8S\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2016-2021 Honda Civic LX:\u003c\/strong\u003e 2.0L L4 Gas (K20C2)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2016-2021 Honda Civic EX:\u003c\/strong\u003e 2.0L L4 Gas (K20C2)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2019-2021 Honda Civic Sport:\u003c\/strong\u003e 2.0L L4 Gas (K20C2)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Honda Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet the exact electrical tolerances of Honda i-VTEC powertrains, this complete kit ensures seamless plug-and-play installation, crisp throttle response, and smooth power delivery across the entire RPM band.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50428874359032,"sku":"DS-E8RA837E3","price":99.95,"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-honda-civic-2016-2021-2-0l-1.jpg?v=1788444993","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-honda-civic-2016-2021-2-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
