B58 Billet/Silicone Coolant Hose Kit

The Vargas Turbocharger Technologies (VTT) Billet/Silicone B58 Coolant Hose Upgrade Kit is designed to replace the failure-prone factory plastic coolant connectors and standard hoses found in Gen 1 B58 F2X/F3X BMW engines. Available in various configurations to suit your needs, customers can choose from a Full Hose Kit, a Radiator Hose Kit, or individual hoses including the Upper Radiator Hose, Lower Radiator Hose, Expansion Tank Hose, and Vent Hose. The kit is offered in three color options: Red, Blue, and Black, allowing for customization to match your engine bay aesthetics. Fitment is primarily for most Gen 1 B58 applications within the F2X and F3X chassis codes. However, VTT notes that they have not test-fit every specific model, and some applications may not be compatible. Installation can be challenging and may require the removal of other engine components to access the hose connections. Each hose is designed to replace specific OEM parts: the Upper Radiator hose (17 12 8 616 548), Lower Radiator hose (17 12 8 633 482), Expansion Tank hose (17 12 8 620 944), and Upper vent hose (17 12 8 616 555). The product comes with a 12-month warranty.
