Heres the difference over a stock coil; they produce more spark energy while consuming less power without sacrificing voltage output. This means you get hotter spark at the plug to burn the maximum amount of fuel in each cylinder while using less power from your electrical system. For Coyote or Hemi combinations currently using Holley EFI or Terminator X, use Smart Coil Ignition Harnesses 558-312 \u0026amp; Coil Extension Harnesses 558-326 for a plug and play solution.  For new Holley EFI installations on Coyote engines, use with Holley EFI Coyote TI-VCT Main Harness for Smart Coils 558-122 \u0026amp; Smart Coil Ignition Harness 558-312 for a plug and play solution.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDirect bolt-on to factory valve covers\u003c\/li\u003e\n\u003cli\u003eSame wiring pinout as other IGN-1A coils for easy plugin upgrades (Will not work with factory wiring)\u003c\/li\u003e\n\u003cli\u003eMore spark energy than any other smart coil on the market for maximum fuel burn during combustion sequence\u003c\/li\u003e\n\u003cli\u003eLow current draw means less demand on the electrical and charging system\u003c\/li\u003e\n\u003cli\u003eBuilt-in ignitor for compatibility with Holley EFI and many other aftermarket ECU’s\u003c\/li\u003e\n\u003cli\u003eMaximum operating voltage of 18 volts – for compatibility with both 12 volt and 16 volt electrical systems found in many performance\/race applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: \u003cspan\u003eHolley EFI\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eCategory\u003c\/strong\u003e: \u003cspan\u003eIgnition\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eCoil Shape\u003c\/strong\u003e: \u003cspan\u003eRound\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eCoil Wire Included\u003c\/strong\u003e: \u003cspan\u003eNo\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: \u003cspan\u003eBlack\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eConnector Gender\u003c\/strong\u003e: \u003cspan\u003eMale Female\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eEmission Code\u003c\/strong\u003e: \u003cspan\u003e3\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eGrade Type\u003c\/strong\u003e: \u003cspan\u003ePerformance\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eMounting Bracket Included\u003c\/strong\u003e: \u003cspan\u003eNo\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eMounting Hardware Included\u003c\/strong\u003e: \u003cspan\u003eYes\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003epart type\u003c\/strong\u003e: \u003cspan\u003eIgnition Coil\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: \u003cspan\u003eCoil\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eSub Category\u003c\/strong\u003e: \u003cspan\u003eIgnition Coil\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eWarning\u003c\/strong\u003e: \u003cspan\u003eCalifornia Proposition 65\u003c\/span\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Holley EFI","offers":[{"title":"Default Title","offer_id":47328200786058,"sku":"HOLEFI-556-161","price":849.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0706\/0619\/2778\/files\/0_556-161_01_normalized.jpg?v=1776464729","url":"https:\/\/www.onlyinstock.com\/products\/holley-efi-556-161-efi-coyote-smart-coil-set","provider":"Only In Stock","version":"1.0","type":"link"}
