Over time, the OEM internal primary and secondary windings suffer dielectric breakdown, leading to insulation punch-through, erratic spark delivery, and persistent P0300 through P0306 misfire codes under load. Worn plug electrodes widen the spark gap, forcing weakened factory coils to operate past their breakdown voltage threshold, ultimately leading to unburned hydrocarbons and lost fuel economy.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete ignition kit features direct-replacement coil-on-plug units engineered with high-dielectric epoxy potting and reinforced thermoplastic housings to resist thermal fatigue and eliminate internal arcing. Paired with laser-welded Denso platinum spark plugs, the system reduces the voltage required to jump the electrode gap, providing stable flame front propagation across the entire RPM band. The platinum center electrode resists erosion under sustained heavy engine loads, ensuring stable idle dynamics and clean throttle tip-in.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e6 High Performance Ignition Coils (Replaces 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;\"\u003e2006-2008 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\u003eJ35A9\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;\"\u003e247 hp \/ 245 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\u003cstrong\u003eUF400\u003c\/strong\u003e\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\u003e2006 Honda Ridgeline 3.5L V6 (RT, RTS, RTL)\u003c\/li\u003e\n  \u003cli\u003e2007 Honda Ridgeline 3.5L V6 (RT, RTS, RTL, RTX)\u003c\/li\u003e\n  \u003cli\u003e2008 Honda Ridgeline 3.5L V6 (RT, RTS, RTL, RTX)\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 YK1 Ridgeline?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2006-2008 Honda Ridgeline equipped with the \u003cstrong\u003eJ35A9\u003c\/strong\u003e 3.5L V6 engine; it is not compatible with later 2009+ J35Z5 configurations.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need secondary ignition plug wires with this kit?\u003c\/h4\u003e\n\u003cp\u003eNo, the \u003cstrong\u003eJ35A9\u003c\/strong\u003e relies entirely on individual coil-on-plug units; torque spark plugs to factory spec (13 lb-ft) and secure coil hold-down bolts hand-tight without over-torquing.\u003c\/p\u003e\n\n\u003ch3\u003eThe Honda Truck Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle sustained payload hauling and trail towing, this direct-fit ignition overhaul kit preserves critical low-end torque output without triggering false ECU misfire thresholds.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67562509172984,"sku":"DS-E6CQMS7CH","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-ridgeline-2006-2008-3-5l-1.jpg?v=1790982937","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-spark-plugs-for-honda-ridgeline-2006-2008-3-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
