On the S58, the coolant problem usually isn't the rubber hoses. It's the plastic quick-connect fittings on their ends, which weaken, crack or fail with heat. VTT's kit swaps those hoses for 6-ply silicone with billet aluminum connectors and fits in place of several factory hose and connector assemblies.
What you get
- 6-ply silicone hoses to replace multiple factory coolant hoses.
- CNC-machined billet aluminum connectors instead of the plastic quick-connects.
- Buy the full kit or just what you need. Choose the Full Hose Kit (priced 15% below the hoses separately), the Radiator Hose Kit, or single hoses: #1 lower radiator, #3 upper radiator, #7 expansion tank to water pump, #13 charge cooler feed, #14 charge cooler vent, #15 expansion tank to cylinder head vent, or #18 cylinder head to water pump inlet. The numbers follow BMW's cooling system diagram.
- Four colors: Black, Red, Blue or Orange.
Good to know
- VTT launched the kit in black first. Check with us on stock before ordering red, blue or orange.
