Intake NCY (35mm) GY6 125-150cc

Référence: 1300-1070.10

État Nouveau

Les collecteurs d'admission NCY offrent un alésage lisse et un diamètre d'admission supérieur au stock. Ensemble, ces deux atouts permettent à votre cylindre d’avoir plus d’air et de carburant, vous donnant plus de puissance. La mise à niveau de la tubulure d'admission est indispensable pour les carburateurs plus gros. Cela n’a aucun sens d’installer un gros carburateur uniquement pour limiter son débit par le collecteur. Les collecteurs plus grands peuvent eux-mêmes augmenter considérablement la puissance et constituent une option de choix par rapport aux collecteurs en caoutchouc standard. Pièces durables et plus de puissance. C'est gagnant-gagnant. CARACTÉRISTIQUES: Collecteur d'admission en aluminium moulé avec revêtement en PTFE Un raccord à vide Un raccord à joint EGR Base. DIMENSIONS: Alésage côté moteur: Alésage côté carbé de 26.5mm: Longueur de canal de 30mm: 100mm. Lors de l'installation d'un carburateur et / ou d'un collecteur d'admission plus gros, veuillez vérifier que le diamètre du moteur du carburateur est bien ajusté dans le collecteur.
