Over time, internal epoxy insulation breaks down, copper windings develop micro-shorts, and aged silicone boots lose dielectric resistance. Concurrently, factory spark plug gaps erode, elevating secondary coil voltage requirements until the ignition system arcs internally. This breakdown triggers erratic spark delivery, unburnt hydrocarbon build-up, catalyst degradation, intermittent Check Engine Lights (CEL), and noticeable roughness across the \u003cstrong\u003eRR1\u003c\/strong\u003e chassis drivetrain.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis service kit restores factory ignition architecture using direct-fit 3-terminal pencil coil-on-plug modules paired with fine-wire iridium-tipped spark plugs. The ignition coils incorporate high-grade dielectric PBT housings and thermal-resistant silicone boots to seal deep plug wells against moisture and oil flashover. Matched with fine-wire iridium center electrodes and dense nickel-alloy ground electrodes gapped to 1.0–1.1 mm, the plugs require significantly lower breakdown voltage. This reduction in electrical stress relieves the ignition drivers, ensures consistent flame kernel development, and resolves intermittent misfires under load.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e6 Pencil-Style Ignition Coils (3-Terminal)\u003c\/li\u003e\n  \u003cli\u003e6 Iridium-Tip Spark Plugs (Pre-gapped 1.0–1.1 mm)\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;\"\u003e2004-2012 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\u003eRR1\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\u003e12137551260\u003c\/strong\u003e, \u003cstrong\u003e12131712219\u003c\/strong\u003e, \u003cstrong\u003e12131712223\u003c\/strong\u003e, \u003cstrong\u003eUF667\u003c\/strong\u003e, \u003cstrong\u003eUF-667\u003c\/strong\u003e, \u003cstrong\u003eMIU12783\u003c\/strong\u003e, \u003cstrong\u003eBKR6EGP\u003c\/strong\u003e, \u003cstrong\u003e5C1476\u003c\/strong\u003e, \u003cstrong\u003eUF522\u003c\/strong\u003e, \u003cstrong\u003eE534A\u003c\/strong\u003e, \u003cstrong\u003eUF44\u003c\/strong\u003e, \u003cstrong\u003eUF515\u003c\/strong\u003e\n\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\u003e2004-2012 Rolls Royce Phantom Base 6.75L V12\u003c\/li\u003e\n  \u003cli\u003e2008-2012 Rolls Royce Phantom Drophead Coupe 6.75L V12\u003c\/li\u003e\n  \u003cli\u003e2008-2012 Rolls Royce Phantom Coupe 6.75L V12\u003c\/li\u003e\n  \u003cli\u003e2005-2012 Rolls Royce Phantom Extended Wheelbase (EWB) 6.75L V12\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 RR1 Phantom?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2004-2012 Rolls Royce Phantom equipped with the \u003cstrong\u003eN73B68\u003c\/strong\u003e 6.75L V12 engine; please note that the V12 requires 12 coils and 12 plugs total, meaning this 6-cylinder kit services one single bank and two kits are required for a complete overhaul.\u003c\/p\u003e\n\n\u003ch4\u003eShould spark plugs and ignition coils always be replaced at the same time?\u003c\/h4\u003e\n\u003cp\u003eYes, replacing both components simultaneously prevents premature secondary coil insulation breakdown caused by widened, worn spark plug gaps.\u003c\/p\u003e\n\n\u003ch3\u003eThe Rolls Royce Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEuropean luxury V12 platforms demand precise primary resistance matching to operate without triggering sensitive secondary DME ignition fault codes.
