The rear cylinder bank is trapped against the firewall, subjecting coil packs to excessive heat soak. Over time, factory coil insulation degrades, leading to dielectric breakdown and micro-arcing within the boots. Compounding this, aged spark plug electrodes experience gap widening from continuous high-voltage discharge. This gap erosion strains the coil-on-plug modules, causing sluggish acceleration, rough idle, poor fuel economy, and eventual multi-cylinder misfires (DTC P0300–P0306).\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis service kit resolves secondary ignition collapse by utilizing high-conductivity copper windings potted in vacuum-sealed epoxy to prevent thermal-shock degradation. The replacement boots use high-temp silicone compounds that resist flashover voltage. Paired with fine-wire iridium spark plugs featuring trivalent metal plating to prevent thread seizure in aluminum cylinder heads, this kit ensures a stable spark kernel under demanding load conditions, matching factory dwell settings and keeping the engine running within proper AFR targets.\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; margin-bottom: 20px;\"\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;\"\u003e2014-2020 Acura RLX\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\u003eJ35Y4\u003c\/strong\u003e \/ \u003cstrong\u003eKC1, KC2\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;\"\u003e310 hp \/ 272 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\u003e305205G0A01\u003c\/strong\u003e, \u003cstrong\u003eUF713\u003c\/strong\u003e, \u003cstrong\u003eKIN133325TOP\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2014-2020 Acura RLX Base 3.5L V6 (J35Y4 \/ KC1)\u003c\/li\u003e\n  \u003cli\u003e2014-2020 Acura RLX Technology Package 3.5L V6 (J35Y4 \/ KC1)\u003c\/li\u003e\n  \u003cli\u003e2014-2020 Acura RLX Advance Package 3.5L V6 (J35Y4 \/ KC1)\u003c\/li\u003e\n  \u003cli\u003e2014-2020 Acura RLX Sport Hybrid SH-AWD 3.5L V6 (J35Y4 \/ KC2)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the KC1 \/ KC2 RLX?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2014-2020 Acura RLX equipped with the \u003cstrong\u003eJ35Y4\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo these iridium plugs come pre-gapped?\u003c\/strong\u003e\u003cbr\u003e Yes, these plugs are pre-gapped to OEM specification, requiring no adjustment prior to installation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Acura Caliber\u003c\/h3\u003e\n\u003cp\u003eThe J-series powertrain relies on clean combustion to maintain its smooth torque delivery and VTEC engagement across the entire powerband.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50593989722360,"sku":"DS-EF626TCZ5","price":112.95,"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-acura-rlx-2014-2020-3-5l-1.jpg?v=1790055309","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-acura-rlx-2014-2020-3-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
