VTT Billet/Silicone Coolant Hoses for F2X/F3X B58

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. Application chart below.

They may not fit some models, we have not test fit on all models.

Please bear in mind, the B58 coolant hoses can be difficult to install, and may require removal of other items on the engine to reach the hose connections.

We will be offering them in a variety of ways.
