Au fur et à mesure que le moteur subit d'innombrables vagues de chaleur, l'époxy interne et les enroulements primaires OEM se dégradent, entraînant une augmentation de la résistance électrique. Ce stress thermique se traduit finalement par une étincelle faible, des ratés d'allumage intermittents sous charge, un ralenti instable et une consommation de carburant diminuée. De plus, les bougies d'origine en cuivre ou en platine usent naturellement leur écartement d'électrode, exacerbant le stress exercé sur les bobines vieillissantes et déclenchant fréquemment les redoutables codes de voyant moteur P0300.\u003c\/p\u003e\n\n\u003ch3\u003eLa solution d'ingénierie\u003c\/h3\u003e\n\u003cp\u003eCe kit d'allumage amélioré résout ces points de défaillance thermique et électrique en utilisant des fils de cuivre internes robustes dans les bobines, réduisant considérablement la résistance et la génération de chaleur.
