Over time, thermal cycling degrades the factory coil pack silicone boots and breaks down internal primary and secondary copper windings. Micro-fractures in the coil epoxy lead to dielectric breakdown, bleeding voltage to the cylinder head rather than the plug gap. Combined with widened gaps on worn factory plugs, this high resistance overburdens the ignition system, resulting in severe high-load misfires, erratic idle, and protective ECU torque intervention.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive ignition service kit addresses high cylinder pressure demands with heavy-duty construction. The six pencil ignition coils feature high-grade magnetic steel cores paired with reinforced epoxy potting to resist thermal degradation and internal short-circuiting. The matching iridium spark plugs feature a fine-wire 0.6mm iridium-alloy center electrode and laser-welded ground electrode. This design dramatically lowers the required ignition firing voltage, maintains quenching resistance against boosted air-fuel charges, and prevents carbon fouling under demanding operational cycles.\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;\"\u003e2000-2002 Audi S4\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\u003eAPB 2.7L Bi-Turbo V6\u003c\/strong\u003e \/ \u003cstrong\u003eB5\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;\"\u003e250 hp \/ 258 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\u003e88921389\u003c\/strong\u003e, \u003cstrong\u003eUF290\u003c\/strong\u003e, \u003cstrong\u003eUF290T\u003c\/strong\u003e, \u003cstrong\u003eKIN133699TOP\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\u003e2000 Audi S4 Base Sedan 2.7L V6 Gas DOHC Turbocharged (APB)\u003c\/li\u003e\n  \u003cli\u003e2001 Audi S4 Base Sedan 2.7L V6 Gas DOHC Turbocharged (APB)\u003c\/li\u003e\n  \u003cli\u003e2001 Audi S4 Avant Wagon 2.7L V6 Gas DOHC Turbocharged (APB)\u003c\/li\u003e\n  \u003cli\u003e2002 Audi S4 Base Sedan 2.7L V6 Gas DOHC Turbocharged (APB)\u003c\/li\u003e\n  \u003cli\u003e2002 Audi S4 Avant Wagon 2.7L V6 Gas DOHC Turbocharged (APB)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the B5 S4?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2000-2002 Audi S4 equipped with the \u003cstrong\u003eAPB\u003c\/strong\u003e 2.7L twin-turbocharged V6 engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo these iridium spark plugs require gapping prior to installation?\u003c\/strong\u003e\u003cbr\u003e While pre-gapped for factory spec, plug gaps should always be verified with a feeler gauge to match your specific boost and calibration levels.\u003c\/p\u003e\n\n\u003ch3\u003eThe Audi Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet rigorous German factory tolerances, this direct-fit ignition system restores smooth idle dynamics, protects catalytic converters, and ensures complete, reliable combustion cycles without triggering check engine lights or misfire fault codes.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50594719138040,"sku":"DS-EMOOSTZII","price":91.95,"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-audi-s4-2000-2002-2-7l-1.jpg?v=1790059338","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-audi-s4-2000-2002-2-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
