Over time, the internal epoxy insulation degrades, creating microscopic fractures that allow secondary voltage to arc to ground rather than jumping the plug gap. Simultaneously, aged spark plugs experience center electrode erosion, widening the gap and placing excessive electrical load on the coil windings.

The coils are engineered with high-conductivity copper primary and secondary windings potted in dense dielectric epoxy, maximizing insulation resistance and thermal dissipation. Heavy-duty silicone boots resist heat-hardening and oil contamination in the plug tubes. The included iridium spark plugs lower the required ionization voltage, ensuring rapid flame front propagation, clean combustion under load, and extended service intervals.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e6x Black Coil-on-Plug Ignition Coils (3-Pin Terminals)\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: 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;\"\u003e3.5L J35A4 \/ J35A6 \/ J35A9 V6 \/ \u003cstrong\u003eYF1\u003c\/strong\u003e, \u003cstrong\u003eYF2\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;\"\u003e244 hp \/ 240 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\u003eUF400\u003c\/strong\u003e, 673-2302, \u003cstrong\u003e30520-PGK-A01\u003c\/strong\u003e, \u003cstrong\u003e30520-PVF-A01\u003c\/strong\u003e, \u003cstrong\u003e30520-PVJ-A01\u003c\/strong\u003e, 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\u003e2003-2008 Honda Pilot LX 3.5L V6 (FWD \/ AWD)\u003c\/li\u003e\n  \u003cli\u003e2003-2008 Honda Pilot EX 3.5L V6 (FWD \/ AWD)\u003c\/li\u003e\n  \u003cli\u003e2005-2008 Honda Pilot EX-L 3.5L V6 (FWD \/ AWD)\u003c\/li\u003e\n  \u003cli\u003e2008 Honda Pilot Special Edition \u0026amp; Value Package 3.5L V6\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\/YF2 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 across all trims and drivetrain options.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to apply dielectric grease during installation?\u003c\/h4\u003e\n\u003cp\u003eApplying a thin coat of dielectric grease to the inside rim of the silicone boots prevents moisture intrusion, flashover arcing, and boot tearing during future removal.\u003c\/p\u003e\n\n\u003ch3\u003eThe Honda Utility Caliber\u003c\/h3\u003e\n\u003cp\u003eThe first-generation Pilot relies on balanced V6 torque for family hauling and moderate towing.
