Over time, engine bay heat soak degrades the internal epoxy resin and primary\/secondary copper windings inside the factory coil packs. This thermal stress causes micro-arcing, internal shorting, and reduced spark voltage under high boost pressure. Compounding this, worn factory spark plug gaps widen due to electrode erosion, drastically increasing the required firing voltage and leading to intermittent misfires, rough idle, and unburned hydrocarbon fouling under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive service kit includes five precision-wound coil-on-plug assemblies paired with five fine-wire iridium spark plugs. The ignition coils feature high-conductivity copper windings sealed with premium dielectric epoxy insulation to resist high-temperature breakdown and voltage leakage. Direct-fit blade terminals eliminate signal resistance. The matched iridium spark plugs utilize ultra-fine center electrodes to lower required ignition voltage, ensuring reliable arc initiation, optimal flame front propagation, stable cylinder pressures, and consistent cold-start characteristics.\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;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2004-2009 Volvo S60 2.5L Inline-5\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eB5254T2 (Modular Engine) \/ P2 Platform\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e208 hp \/ 236 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eUF517, 30713417, 307134170, E1017, GN10331\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2004-2009 Volvo S60 2.5T (2.5L L5 Turbo)\u003c\/li\u003e\n  \u003cli\u003e2004-2009 Volvo S60 2.5T AWD (2.5L L5 Turbo)\u003c\/li\u003e\n  \u003cli\u003eInterchange: UF517, 30713417, 307134170, E1017, 52-2133, IGC0166, IC597, C-780, GN10331, 178-8383, C1721\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Volvo Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet stringent European engine management requirements, this ignition kit maintains precise secondary resistance tolerances, preventing false knock detection and eliminating check engine lights for smooth, factory-grade throttle response.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50448857006328,"sku":"DS-E8DDX79TY","price":107.95,"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-s60-2004-2009-2-5l-1.jpg?v=1788661998","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-and-iridium-spark-plugs-for-volvo-s60-2004-2009-2-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
