Constant engine bay heat soak causes the factory epoxy encapsulation in the ignition coils to micro-fracture, leading to high-voltage dielectric breakdown and internal resistance spikes. Compounded by widened electrode gaps on eroded factory plugs, weak secondary voltage results in unburnt hydrocarbon blowby, sluggish throttle response, and catalyst-damaging misfire codes under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-fit replacement package restores proper secondary spark voltage using precision-wound internal copper coils potted in heat-resistant dielectric epoxy. Built to meet or exceed OEM specifications, these direct-replacement coils maintain uniform dwell times and prevent voltage leakage across high operating temperatures. Paired with NGK spark plugs engineered with corrosion-resistant plated shells and wear-resistant electrodes, this combination ensures sharp flame-front propagation, smooth throttle tip-in, and reliable ignition across the entire RPM band.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e3 Ignition Coils\u003c\/li\u003e\n  \u003cli\u003e6 NGK Spark Plugs\u003c\/li\u003e\n\u003c\/ul\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: solid font-size: min-width:\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;\"\u003e1995-1999 Oldsmobile Aurora\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\u003e4.0L L47 V8\u003c\/strong\u003e \/ \u003cstrong\u003eG-Body\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 \/ 260 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\u003eD546\u003c\/strong\u003e, \u003cstrong\u003e5C1077\u003c\/strong\u003e, \u003cstrong\u003eE219\u003c\/strong\u003e, \u003cstrong\u003e52-1693\u003c\/strong\u003e, \u003cstrong\u003eIC406\u003c\/strong\u003e, \u003cstrong\u003e1106008\u003c\/strong\u003e, \u003cstrong\u003eDR-47\u003c\/strong\u003e, \u003cstrong\u003e1103646\u003c\/strong\u003e, \u003cstrong\u003e11037\u003c\/strong\u003e, \u003cstrong\u003eDR39\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\u003e1995-1999 Oldsmobile Aurora 4.0L\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the G-Body Aurora?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1995-1999 Oldsmobile Aurora equipped with the \u003cstrong\u003e4.0L L47\u003c\/strong\u003e engine; always verify your original coil connector style and quantity before installation.\u003c\/p\u003e\n\n\u003ch4\u003eAre spark plug wires included in this service kit?\u003c\/h4\u003e\n\u003cp\u003eNo, spark plug wires are not included in this kit; torque new plugs to factory specifications and inspect your existing secondary ignition leads prior to assembly.\u003c\/p\u003e\n\n\u003ch3\u003eThe Oldsmobile Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to deliver smooth, executive-tier power delivery, this ignition kit restores the factory refinement and highway-cruising confidence expected from the classic luxury cruiser.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67561485074680,"sku":"DS-E4ONJH0DQ","price":109.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-spark-plugs-for-oldsmobile-aurora-1995-1999-4-0l-1.jpg?v=1790964169","url":"https:\/\/performancechiptuning.com\/de\/products\/ignition-coil-spark-plugs-for-oldsmobile-aurora-1995-1999-4-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
