Upgrade the weak original coolant connectors on the BMW S58 engine

The weakest point in the original cooling system of the BMW S58 engine is not the rubber hoses, but the OEM plastic quick-connect fittings . Over time, these plastic fittings can weaken, crack or break – especially under conditions of high thermal load and performance use.

VTT offers an updated 6-layer silicone coolant hose kit for the BMW S58 platform. The kit features CNC-machined billet aluminum connectors that significantly improve durability, reliability, and long-term performance compared to the original plastic parts.

The kit is designed as a direct replacement for several original coolant hoses and connector assemblies found in the original BMW cooling system diagram.

In addition to improving reliability, silicone hoses also bring a sportier and more finished look to the engine bay , giving the S58 engine an even more performance-oriented appearance.

Features

• 6-layer reinforced silicone construction

• CNC machined billet aluminum connectors

• Replaces weak OEM plastic quick connectors

• Designed for the BMW G8X platform (S58 engine)

• Improves cooling system durability and reliability

• A stylish upgrade to the appearance of the engine compartment
