VTT Billet/Silicone B58 F2X/F3X Coolant Hoses

VTT is proud to announce our B58 Gen 1 Billet/Silicone coolant hose upgrade kit! The factory plastic coolant connectors are prone to breaking over time, and the hoses are just your standard run-of-the-mill coolant hose. We wanted to provide an upgrade to both areas. What we came up with is Billet 6061-T6 connectors anodized black for corrosion resistance, and 6-ply silicone molded silicone hoses in the factory shapes.

Currently, these fit most Gen 1 B58 applications F2X/F3X. They may not fit some models, we have not test fit on all models.

We will be offering them in a variety of ways.
