The sustained engine bay heat generated by the 4.4L M62 degrades the rubber boot seals, facilitating high-voltage flashover to the cylinder head rather than across the plug gap. Concurrently, aged spark plug electrodes experience severe gap widening and erosion, drastically raising coil load and causing cylinder misfires, hesitation under load, and uneven idle.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement kit pairs eight high-output ignition coils with fine-wire laser-welded iridium spark plugs. The coils feature durable internal copper primary and secondary windings encased in high-temperature thermoplastic housings to prevent thermal failure and electrical cross-talk. The matched iridium spark plugs offer superior thermal conductivity and a lower ignition voltage demand, resisting electrode erosion and eliminating quench effects to ensure stable flame kernel expansion.\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;\"\u003e1996-2001 BMW 7 Series (4.4L V8)\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;\"\u003eM62B44 \/ M62TUB44 \/ E38\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;\"\u003e282 hp \/ 324 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eUF354, UF-354, UF300, UF-300\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1996-2001 BMW 740i Base Sedan 4-Door 4.4L 4398CC V8 GAS DOHC Naturally Aspirated\u003c\/li\u003e\n  \u003cli\u003e1996-2001 BMW 740iL Base Sedan 4-Door 4.4L 4398CC V8 GAS DOHC Naturally Aspirated\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe BMW Precision Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to exact German OE tolerances, this ignition service kit prevents OBD-II misfire fault codes, protects downstream catalytic converters from unburned fuel wash, and guarantees the vibration-free powertrain operation expected of the flagship E38 platform.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50458916126968,"sku":"DS-EKZOT6TU8","price":149.95,"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-bmw-7-series-1996-2001-4-4l-1.jpg?v=1788803434","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-bmw-7-series-1996-2001-4-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
