Over repeated thermal cycles, factory epoxy potting develops micro-fissures, weakening internal winding insulation and triggering dielectric breakdown. This causes intermittent secondary voltage leakage, carbon tracking down the plug wells, and premature spark dissipation. Paired with aged spark plugs suffering electrode erosion and gap enlargement, the weakened coils trigger diagnostic trouble codes **P0300** through **P0306**, stumble under acceleration, and degrade overall combustion efficiency.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive tune-up kit replaces deteriorated components with high-dielectric epoxy-potted coils and fine-wire iridium spark plugs. Each coil assembly features an oil- and heat-resistant silicone boot paired with durable 3-pin factory-style connectors to eliminate external arc flashover. The companion iridium spark plugs feature a laser-welded fine-wire center electrode requiring lower firing voltage while maintaining superior thermal conductivity and gap stability under load. This engineered pairing ensures rapid flame kernel development, suppresses quench effects, and maintains stable ignition timing across the entire powerband.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e6 Ignition Coils (Black, 3-Pin Connector)\u003c\/li\u003e\n  \u003cli\u003e6 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: 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;\"\u003e2001-2009 Acura MDX\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;\"\u003e3.5L J35, 3.7L J37 \/ YD1, YD2\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;\"\u003e240-300 hp \/ 245-275 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, 673-2302, 30520-PGK-A01, 30520-PVF-A01, 30520-PVJ-A01, 30520PGKA01, 30520PVFA01, 30520PVJA01, GN10168, 5C1451, C1460, C1576, E420, DQ50132A, 0 986 AG0 512, 1788359\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\u003e2001-2006 Acura MDX Base \/ Touring 3.5L V6 (YD1 Chassis, J35 Engine)\u003c\/li\u003e\n  \u003cli\u003e2007-2009 Acura MDX Base 3.7L V6 (YD2 Chassis, J37 Engine)\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 YD1 and YD2 MDX?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2001-2009 Acura MDX equipped with the **J35A3**, **J35A5**, and **J37A1** V6 engines.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need dielectric grease during installation?\u003c\/h4\u003e\n\u003cp\u003eApplying a thin film of dielectric grease to the inside of the spark plug boots aids moisture sealing and prevents the boot from adhering to the ceramic insulator during future servicing.\u003c\/p\u003e\n\n\u003ch3\u003eThe Acura Engineering Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle the high-rpm demands of VTEC valvetrain architecture, this complete ignition service kit delivers consistent, high-energy spark delivery to preserve smooth power distribution and clean combustion.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67998042685688,"sku":"DS-E3N1BJBHS","price":134.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-spark-plugs-for-acura-mdx-2001-2009-3-5l-3-7l-1.jpg?v=1794001259","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-spark-plugs-for-acura-mdx-2001-2009-3-5l-3-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
