Vargas Turbo Technologies VTT BMW B58 Coolant Hose Kit for F2X/F3X (F20 F21 F22 F23 F30 F31 F32 F33 F36) Billet 6061-T6 Ends & 6‑Ply Silicone Upper/Lower/Expansion/Vent M140i M240i 340i 440i Gen 1

B58 F-series silicone coolant line upgrade with CNC alloy ends

Strengthen the cooling system on your F-chassis B58 with this premium silicone coolant line set from VTT. It replaces fragile plastic quick-connect hoses with CNC machined 6061-T6 aluminium ends and tough six-layer silicone, shaped to the factory routing for an easy, direct fit. Perfect for remapped daily drivers, fast road builds and track day cars that demand reliability, temperature control and long service life.

We have fitted these in our Warwickshire workshop and they have been flawless. Customers love the cleaner look, the OE-style fit, and the confidence that comes from ditching brittle plastic fittings for robust alloy hardware.
