Over thermal cycling, factory pencil coil internal epoxy insulation degrades, creating internal winding shorts and micro-arcing. This secondary resistance breakdown triggers secondary ignition decay, resulting in unburnt fuel, catalytic converter stress, intermittent hesitation under load, and bank-specific OBD-II misfire codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered for direct replacement on the \u003cstrong\u003eN73B68\u003c\/strong\u003e architecture, these pencil-style coil-on-plug units feature high-dielectric epoxy potting and copper primary\/secondary windings to prevent thermal dielectric breakdown. Each unit incorporates a high-tear-strength silicone spark plug boot to seal against moisture and oil vapor in deep plug wells. The 3-terminal blade connector couples seamlessly with the factory harness, restoring steady spark energy without harness splicing or ECU adaptation.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e6 x Direct-Fit Pencil Ignition Coils with Integrated Silicone Spark Plug Boots\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;\"\u003e2009-2012 Rolls Royce Phantom\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\u003eN73B68\u003c\/strong\u003e 6.75L V12 \/ \u003cstrong\u003eRR01\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;\"\u003e453 hp \/ 531 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\u003e12138616153\u003c\/strong\u003e, \u003cstrong\u003e12137594596\u003c\/strong\u003e, UF667, 178-8508, 178-8522, 0221504464, 0221504470, 0221504800, C1404, C1477, C1638, C1795, C1826, GN10328, GN10571, IC770, U5272, 5C1476, 5C1695, E1167\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 Rolls Royce Phantom Base \/ EWB 6.75L V12 (N73B68)\u003c\/li\u003e\n  \u003cli\u003e2010 Rolls Royce Phantom Base \/ EWB 6.75L V12 (N73B68)\u003c\/li\u003e\n  \u003cli\u003e2011 Rolls Royce Phantom Base \/ EWB 6.75L V12 (N73B68)\u003c\/li\u003e\n  \u003cli\u003e2012 Rolls Royce Phantom Base \/ EWB 6.75L V12 (N73B68)\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\u003eRR01\u003c\/strong\u003e Phantom?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2009-2012 Rolls Royce Phantom equipped with the \u003cstrong\u003eN73B68\u003c\/strong\u003e engine.
