As internal windings break down and spark plug electrodes erode, coil resistance spikes. This thermal stress leads to voltage punch-through, spark blowout under heavy load, and recurring P0300–P0306 diagnostic trouble codes. Neglected coils and worn plugs cause stumbling under acceleration, rough idle, unburned hydrocarbon wash, and reduced fuel economy.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive tune-up kit replaces all primary and secondary wear components in a single service. The ignition coils feature high-temperature silicone boots, precision-formed internal magnetic cores, and high-dielectric epoxy filling to resist vibration and core saturation. Paired with fine-wire iridium spark plugs, the assembly lowers required arc-over firing voltage, promoting faster flame kernel growth and consistent combustion during high-load hauling and towing conditions.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e6x Black Coil-on-Plug Ignition Coils\u003c\/li\u003e\n  \u003cli\u003e6x Fine-Wire Iridium 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: 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;\"\u003e2009-2014 Honda Ridgeline\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\u003eJ35Z5\u003c\/strong\u003e \/ \u003cstrong\u003eYK1\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;\"\u003e250 hp \/ 247 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;\"\u003e\n\u003cstrong\u003eUF603\u003c\/strong\u003e, \u003cstrong\u003eUF-603\u003c\/strong\u003e, \u003cstrong\u003e30520-R70-A01\u003c\/strong\u003e, \u003cstrong\u003e30520R70A01\u003c\/strong\u003e, \u003cstrong\u003e30520-R70-S01\u003c\/strong\u003e, \u003cstrong\u003e30520R70S01\u003c\/strong\u003e, \u003cstrong\u003e5C1681\u003c\/strong\u003e, \u003cstrong\u003eE1103\u003c\/strong\u003e, \u003cstrong\u003e52-2036\u003c\/strong\u003e, \u003cstrong\u003eIC693\u003c\/strong\u003e, \u003cstrong\u003eC1624\u003c\/strong\u003e, \u003cstrong\u003eCM11-213\u003c\/strong\u003e, \u003cstrong\u003e90207-RAA-A01\u003c\/strong\u003e, \u003cstrong\u003eIZFR6K-11S\u003c\/strong\u003e\n\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\u003e2009-2014 Honda Ridgeline RT (3.5L V6 \u003cstrong\u003eJ35Z5\u003c\/strong\u003e)\u003c\/li\u003e\n  \u003cli\u003e2009-2014 Honda Ridgeline RTS (3.5L V6 \u003cstrong\u003eJ35Z5\u003c\/strong\u003e)\u003c\/li\u003e\n  \u003cli\u003e2009-2014 Honda Ridgeline RTL (3.5L V6 \u003cstrong\u003eJ35Z5\u003c\/strong\u003e)\u003c\/li\u003e\n  \u003cli\u003e2012-2014 Honda Ridgeline Sport (3.5L V6 \u003cstrong\u003eJ35Z5\u003c\/strong\u003e)\u003c\/li\u003e\n  \u003cli\u003e2014 Honda Ridgeline SE (3.5L V6 \u003cstrong\u003eJ35Z5\u003c\/strong\u003e)\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 \u003cstrong\u003eYK1\u003c\/strong\u003e Ridgeline?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2009-2014 Honda Ridgeline equipped with the 3.5L \u003cstrong\u003eJ35Z5\u003c\/strong\u003e V6 engine across all factory trim levels.\u003c\/p\u003e\n\n\u003ch4\u003eDo the replacement coil boots require dielectric grease during installation?\u003c\/h4\u003e\n\u003cp\u003eYes, applying a thin film of dielectric grease inside the silicone boots prevents moisture intrusion, arcing, and boot adhesion to the spark plug ceramic insulators.\u003c\/p\u003e\n\n\u003ch3\u003eThe Honda Ridgeline Workhorse Standard\u003c\/h3\u003e\n\u003cp\u003eMaintaining peak ignition efficiency in the \u003cstrong\u003eYK1\u003c\/strong\u003e platform ensures your Ridgeline delivers reliable power delivery, consistent cold starts, and full towing capacity under rigorous load demands.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67998173921528,"sku":"DS-EN50EL33W","price":83.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-spark-plugs-for-honda-ridgeline-2009-2014-3-5l-1.jpg?v=1794001517","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-spark-plugs-for-honda-ridgeline-2009-2014-3-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
