Due to sustained underhood heat cycling in the \u003cstrong\u003eB5 \/ B5.5\u003c\/strong\u003e engine bay, the OEM module's epoxy potting and phenolic case suffer micro-fracturing. This thermal breakdown leads to dielectric failure, carbon tracking, and high-voltage arc-over, precipitating persistent P0300 through P0306 DTC misfire codes under load. Compounding this, aged spark plugs widen their gap resistance, accelerating thermal breakdown in the factory coil windings.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive service kit addresses secondary ignition breakdown at both ends of the circuit. The direct-fit coil pack features high-grade copper windings insulated with premium dielectric epoxy resin to resist thermal stress and electrical leakage. Paired with calibrated spark plugs engineered to factory thermal heat ranges, this matched setup optimizes flame kernel propagation, restores clean combustion burn, reduces unburned hydrocarbon loading into the catalytic converters, and maintains stable secondary ignition resistance without throwing fault codes.\u003c\/p\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;\"\u003e1998-2005 Volkswagen Passat\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\u003eAHA, ATQ\u003c\/strong\u003e (2.8L V6) \/ \u003cstrong\u003eB5, B5.5\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;\"\u003e190 hp \/ 206 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\u003e078905104\u003c\/strong\u003e, \u003cstrong\u003eUF256\u003c\/strong\u003e, \u003cstrong\u003eC1171\u003c\/strong\u003e, \u003cstrong\u003eC-684\u003c\/strong\u003e, \u003cstrong\u003eIC381\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\u003e1998-2005 Volkswagen Passat GLS 2.8L V6\u003c\/li\u003e\n  \u003cli\u003e1998-2005 Volkswagen Passat GLX 2.8L V6\u003c\/li\u003e\n  \u003cli\u003e2000-2005 Volkswagen Passat 4Motion 2.8L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the B5 and B5.5 Passat?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1998-2005 Volkswagen Passat equipped with the 2.8L 30V \u003cstrong\u003eAHA\u003c\/strong\u003e and \u003cstrong\u003eATQ\u003c\/strong\u003e engine codes.\u003c\/p\u003e\n\n\u003ch4\u003eAre plug wires included in this overhaul kit?\u003c\/h4\u003e\n\u003cp\u003eNo, this kit includes the direct-mount 6-cylinder waste-spark coil pack and six spark plugs; high-tension secondary ignition wires must be sourced separately if damaged.\u003c\/p\u003e\n\n\u003ch3\u003eThe Volkswagen Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to exact European dwell-time and internal resistance tolerances, this ignition system ensures factory OBD-II signal accuracy, rapid transient throttle response, and uncompromised emissions compliance.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67524630577400,"sku":"DS-EJBCT3QMI","price":112.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-spark-plugs-for-volkswagen-passat-1998-2005-2-8l-1.jpg?v=1790460643","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-spark-plugs-for-volkswagen-passat-1998-2005-2-8l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
