Over decades, factory internal epoxy potting degrades, resulting in dielectric breakdown and micro-arcing within the secondary coil windings. This voltage leakage manifests as intermittent misfires under load, unburnt hydrocarbon accumulation, and premature catalytic converter degradation. Concurrently, traditional worn spark plugs develop enlarged gaps that demand excessive secondary voltage from already fatigued ignition coils.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis service kit resolves weak spark output by pairing high-dielectric replacement coil-on-plug packs with fine-wire iridium spark plugs. The ignition coils feature reinforced thermoplastic housings and heat-resistant internal windings engineered to match factory dwell times and primary resistance specs. Matching these with laser-welded iridium electrode spark plugs lowers the required arc initiation voltage, preserving coil insulation while establishing consistent flame kernel growth across all eight cylinders under hard acceleration.\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: 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;\"\u003e1993-1995 BMW 7 Series\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\u003eM60B40\u003c\/strong\u003e \/ \u003cstrong\u003eE32\u003c\/strong\u003e, \u003cstrong\u003eE38\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;\"\u003e282 hp \/ 295 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\u003eUF226\u003c\/strong\u003e, \u003cstrong\u003e12131703359\u003c\/strong\u003e, \u003cstrong\u003e12131726177\u003c\/strong\u003e, \u003cstrong\u003e12131729842\u003c\/strong\u003e, \u003cstrong\u003e7092\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\u003e1993-1994 BMW 740i (E32) 4.0L V8\u003c\/li\u003e\n  \u003cli\u003e1993-1994 BMW 740iL (E32) 4.0L V8\u003c\/li\u003e\n  \u003cli\u003e1995 BMW 740i (E38) 4.0L V8\u003c\/li\u003e\n  \u003cli\u003e1995 BMW 740iL (E38) 4.0L V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the E32 and E38 7 Series?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1993-1995 BMW 7 Series equipped with the \u003cstrong\u003eM60B40\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the recommended installation torque for these spark plugs?\u003c\/strong\u003e\u003cbr\u003e Torque the iridium spark plugs dry to 25 to 30 Nm (18 to 22 lb-ft) to ensure an airtight combustion seal without stripping the aluminum cylinder head threads.\u003c\/p\u003e\n\n\u003ch3\u003eThe BMW Precision Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to satisfy precise German DME tolerances, this direct-fit ignition system restores balanced cylinder pressure and prevents erratic timing pull or check-engine light illumination across high-speed autobahn runs.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50625992458488,"sku":"DS-EUF11FVV7","price":169.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-iridium-spark-plugs-for-bmw-7-series-1993-1995-4-0l-1.jpg?v=1790353173","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-iridium-spark-plugs-for-bmw-7-series-1993-1995-4-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
