The perfect upgrade for your connection between your thermostat and cylinder head. Designed using durable silicone and billet aluminum to greatly outlast the OE rubber and plastic combination. Some of the weakest points of the cooling systems in BMW's can come down to the OE plastic fittings breaking down from the constant changes in temperature, softening these plastic components. When this happens, even simply moving the hose slightly could cause the fitting to crack, causing the coolant to leak all over. The ECS design silicone hose with billet aluminum adapter retains OE fitment with superior strength to not only handle the performance, but also stand up to the wear and tear of a daily driver. Features: Manufactured from billet 6061-T6 and type III anodized for exceptional durability and corrosion resistance. Much stronger part than OEM plastic Will not become brittle and fatigue over time due to thermal cycling. This will prevent the part from breaking during removal and re-installation. Constructed of 4-Ply reinforced silicone for improved durability over the failure-prone OE rubber hose. Flourosilicone lined internal layer for exceptional chemical resistance. Silicone offers reduced thermal conductivity as well as improved resistance to ozone and UV degradation for improved performance and durability. Follows OEM form for perfect fitment. Utilizes OEM O-ring 11537545278 to ensure a proper seal. Replaces Genuine BMW Part Number: 11537545890
