Au fil du temps, les enroulements internes se dégradent en raison de la chaleur extrême du compartiment moteur, ce qui entraîne une faible propagation de l'étincelle. Cette faiblesse se manifeste par un ralenti irrégulier, une hésitation sous forte accélération et les redoutables codes de ratés d'allumage des cylindres. De plus, les électrodes des bougies d'allumage OEM standard s'usent rapidement sous les pressions intenses des cylindres des moteurs turbocompressés de 1,8 L et 2,0 L, compromettant l'efficacité de la combustion et privant le moteur de puissance et d'économie de carburant potentielles.\u003c\/p\u003e\n  \n  \u003ch3\u003eLa solution technique\u003c\/h3\u003e\n  \u003cp\u003eCe kit d'allumage complet résout les problèmes de ratés d'allumage d'origine en combinant des bobines d'allumage haute performance avec des bougies d'allumage haut de gamme en ruthénium.

Associé aux bougies d'allumage en ruthénium de pointe – qui offrent une durabilité et une résistance à la fusion supérieures à celles de l'iridium ou du platine traditionnels – ce système garantit un calage d'allumage optimal et une combustion complète du carburant.
