Over extended heat cycles, factory coil housings develop micro-fissures in the outer epoxy casing, allowing high-voltage arc leakage directly to the cylinder head rather than the spark plug electrode. Combined with gradual electrode erosion on standard plugs, this resistance increase overburdens the primary windings, resulting in hesitations, P0301-P0305 diagnostic trouble codes, and unburnt fuel degradation of the catalytic converter.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive ignition pack delivers five matched direct-ignition coil assemblies paired with laser-welded iridium spark plugs. Each coil-on-plug unit features high-conductivity internal copper windings insulated with premium dielectric resin to prevent internal shorting under high boost pressures. The accompanying iridium spark plugs maintain a precise spark gap under extreme temperatures, demanding lower firing voltage while providing a stable, efficient flame kernel.\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;\"\u003e2005-2006 Volvo S80\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;\"\u003e2.5L Turbo (B5254T2) \/ 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 (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number \/ Interchanges\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eUF517, 30713417, 307134170, E1017, GN10331, C1721\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2005 Volvo S80:\u003c\/strong\u003e 2.5T, 2.5T AWD (2.5L L5 Turbo B5254T2)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2006 Volvo S80:\u003c\/strong\u003e 2.5T, 2.5T AWD (2.5L L5 Turbo B5254T2)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Volvo Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEuropean engine management demands strict resistance tolerances to prevent false misfire monitoring faults.
