Over drive cycles, factory \u003cstrong\u003eUF400\u003c\/strong\u003e ignition coils suffer thermal degradation of their internal epoxy resin, resulting in dielectric puncture and secondary winding flashover. Concurrently, factory spark plug ground electrodes erode, widening the firing gap and placing excessive inductive load on aging coil packs, presenting as hesitation under load, P0300–P0306 DTC misfire codes, and degraded fuel economy.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete refresh kit pairs six heavy-duty direct-replacement coil-on-plug modules with factory-specified Denso platinum spark plugs. The replacement coils feature high-purity copper windings and high-dielectric epoxy potting to withstand thermal cycling and suppress high-voltage micro-arcing. Paired with fine-wire platinum center electrodes, the system lowers required ionization voltage, delivering rapid kernel development, stable spark duration, and robust arc delivery under high manifold pressure and variable valve timing transitions.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e6 High Performance Ignition Coils (Replacement for UF400)\u003c\/li\u003e\n  \u003cli\u003e6 Denso Platinum Spark Plugs\u003c\/li\u003e\n\u003c\/ul\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: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\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;\"\u003e2003-2008 Honda Pilot\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;\"\u003e\n\u003cstrong\u003eJ35A\u003c\/strong\u003e 3.5L V6 \/ \u003cstrong\u003eYF1\u003c\/strong\u003e\n\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;\"\u003e240–255 hp \/ 240–250 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;\"\u003eUF400, C-541, 30520-PDK-A01, C1460, C1576, C1577, C1519\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\u003e2003-2008 Honda Pilot 3.5L V6 (LX, EX, EX-L, Special Edition)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the YF1 Pilot?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2003-2008 Honda Pilot equipped with the \u003cstrong\u003eJ35A\u003c\/strong\u003e 3.5L V6 engine. \u003cstrong\u003eSpark plug wires are not included or required, as this application uses an independent coil-on-plug setup.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDo the new spark plugs need to be gapped before installation?\u003c\/h4\u003e\n\u003cp\u003eDenso platinum plugs come pre-gapped from the factory, but inspecting the gap and torquing to OEM spec (13 lb-ft) without anti-seize is recommended to maintain correct thread stretch and heat transfer.\u003c\/p\u003e\n\n\u003ch3\u003eThe Honda Workhorse Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle heavy cargo loads and utility towing, refreshing the \u003cstrong\u003eJ35A\u003c\/strong\u003e ignition circuit restores peak combustion stability, ensures smooth power delivery under towing load, and keeps cylinder bank temperatures balanced.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67562484433144,"sku":"DS-EK0DLVQ4B","price":198.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-spark-plugs-for-honda-pilot-2003-2008-3-5l-1.jpg?v=1790981519","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-spark-plugs-for-honda-pilot-2003-2008-3-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
