Après des cycles de chaleur prolongés dans le compartiment moteur, les capuchons des bobines OEM deviennent cassants, perdant leurs propriétés diélectriques isolantes. Cela entraîne des coupures d'étincelles sous pression, des pressions de cylindre incohérentes et une défaillance de la bobine d'allumage primaire. Simultanément, les bougies d'allumage standard subissent une érosion des électrodes, élargissant l'écartement des étincelles, ce qui est directement lié au ralenti irrégulier, aux hésitations lors de l'accélération et aux avertissements inévitables de dysfonctionnement de la transmission.\u003c\/p\u003e\n  \n  \u003ch3\u003eLa solution d'ingénierie\u003c\/h3\u003e\n  \u003cp\u003eCette suite d'allumage de remplacement regroupe quatre bobines d'allumage à haut rendement ainsi que quatre bougies d'allumage performance en iridium soudées au laser, conçues pour dépasser les seuils de fonctionnement d'usine. Les bobines sont dotées d'enroulements primaires et secondaires en cuivre améliorés, enfermés dans une résine époxy avancée, résistant efficacement à l'accumulation de chaleur et minimisant la chute de tension sur toute la plage de régime. Les bougies d'allumage à pointe d'iridium offrent un point de fusion nettement plus élevé que les variantes standard en platine ou en cuivre, maintenant un écartement d'étincelle précis et inaltérable sous des pressions extrêmes dans la chambre de combustion. Ensemble, cette combinaison assure une étincelle de haute intensité et concentrée, favorisant une vaporisation complète du carburant dans le cylindre, une puissance accrue, une délivrance de couple réactive et l'élimination des comportements irréguliers du moteur.\u003c\/p\u003e\n  \n\n  \u003ch3\u003eSpécifications techniques\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\u003eCompatibilité\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eBMW X3 2013-2017\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eMoteur \/ Châssis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eN20 2.0L \/ F25\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePuissance d'origine\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e240 ch \/ 260 lb-pi (approx.)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eNuméro de pièce\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eUF592 \/ 12137594937 \/ 97506\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \n  \u003ch3\u003eCompatibilité\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eBMW X3 2.0L 2013\u003c\/li\u003e\n    \u003cli\u003eBMW X3 2.0L 2014\u003c\/li\u003e\n    \u003cli\u003eBMW X3 2.0L 2015\u003c\/li\u003e\n    \u003cli\u003eBMW X3 2.0L 2016\u003c\/li\u003e\n    \u003cli\u003eBMW X3 2.0L 2017\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eLa norme d'étalonnage BMW\u003c\/h3\u003e\n  \u003cp\u003eConçu strictement pour les tolérances de gestion moteur européennes, ce kit d'allumage s'installe en toute transparence sans déclencher de voyant Check Engine (CEL), restaurant la précision exacte, la stabilité du ralenti et la puissance réactive requises par la plateforme F25.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48238703345912,"sku":"DS-ERZ09CIKR","price":174.95,"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-x3-2013-2017-2-0l-1.jpg?v=1776185328"},{"product_id":"ignition-coil-iridium-spark-plugs-for-bmw-x3-2007-2012-3-0l-i6","title":"Bobine d'allumage et bougies d'allumage Iridium pour BMW X3 (2007-2012) 3.0L I6","description":"\u003ch2\u003eBobine d'allumage de rechange directe et bougies d'allumage en iridium pour BMW X3 2007-2012\u003c\/h2\u003e\n\n\u003cp\u003e\u003cstrong\u003eRétablissement de l'énergie d'allumage et de l'efficacité de combustion optimales :\u003c\/strong\u003e Ce kit d'entretien complet du système d'allumage remplace les bobines d'allumage d'origine dégradées et les bougies usées pour éliminer les ratés d'allumage et restaurer la réponse de l'accélérateur sur les moteurs 3.0L atmosphériques.\u003c\/p\u003e\n\n\u003ch3\u003eLa dégradation de l'allumage du X3 d'origine\u003c\/h3\u003e\n\u003cp\u003eLe six cylindres en ligne N52 3.0L atmosphérique repose fortement sur un calage précis de l'allumage et une forte tension de sortie pour maintenir sa puissance fluide caractéristique. Cependant, les bobines d'allumage d'origine situées en profondeur dans les caches-soupapes E83 et F25 sont soumises à des cycles thermiques incessants.

Associé à des bougies d'allumage en iridium haute performance, ce kit garantit une électrode centrale ultra-fine qui nécessite moins de tension d'allumage pour franchir l'écart. L'alliage d'iridium offre une résistance exceptionnelle à l'érosion par les étincelles et à la corrosion chimique dans la chambre de combustion.
