Over repeated heating and cooling cycles, the factory epoxy potting degrades and develops micro-fractures in the secondary winding insulation. This breakdown causes dielectric breakdown, internal arcing, erratic idle, and high-load misfires (DTCs P0300–P0305). Simultaneously, worn spark plugs widen their factory gap under boost, forcing tired coils to work harder until total circuit failure occurs.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis refresh package pairs five high-output pencil ignition coils with five fine-wire iridium spark plugs to re-establish proper dwell and spark delivery. Each coil is built with premium copper wire windings and high-temperature dielectric casing to withstand extreme cylinder head temperatures without voltage leakage. The matching fine-wire iridium spark plugs lower required firing voltage, offer superior anti-fouling resistance, and maintain precise gap tolerances under boost to ensure clean, consistent flame propagation across all five cylinders.\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;\"\u003e2003-2006 Volvo XC70\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\u003eB5254T2\u003c\/strong\u003e 2.5L Turbo \/ \u003cstrong\u003eP2\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;\"\u003e208 hp \/ 236 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\u003eUF341\u003c\/strong\u003e, \u003cstrong\u003eCUF341\u003c\/strong\u003e, \u003cstrong\u003e91256016\u003c\/strong\u003e, \u003cstrong\u003e30713416\u003c\/strong\u003e, \u003cstrong\u003eGN10334\u003c\/strong\u003e, \u003cstrong\u003e9125601\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\u003e2003 Volvo XC70 2.5T AWD (2.5L L5 Turbo B5254T2)\u003c\/li\u003e\n  \u003cli\u003e2004 Volvo XC70 2.5T AWD (2.5L L5 Turbo B5254T2)\u003c\/li\u003e\n  \u003cli\u003e2005 Volvo XC70 2.5T AWD (2.5L L5 Turbo B5254T2)\u003c\/li\u003e\n  \u003cli\u003e2006 Volvo XC70 2.5T AWD (2.5L L5 Turbo B5254T2)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the P2 XC70?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2003-2006 Volvo XC70 equipped with the \u003cstrong\u003eB5254T2\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre these spark plugs pre-gapped for turbo operation?\u003c\/strong\u003e\u003cbr\u003e Yes, the iridium plugs arrive pre-gapped to factory specifications, though bench-checking the gap prior to installation is standard workshop protocol.\u003c\/p\u003e\n\n\u003ch3\u003eThe Volvo Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to satisfy factory Bosch ME7 engine management parameters, this kit restores smooth idle quality and full transient boost response without triggering false-positive misfire check engine lights.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50603977736440,"sku":"DS-E00KYSPDJ","price":94.95,"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-volvo-xc70-2003-2006-2-5l-1.jpg?v=1790088562","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-volvo-xc70-2003-2006-2-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
