CRP Automotive introduces two upgraded Rein Coolant Hose Metal Connectors (CRP Part Nos. CHU0940 & CHK0940) designed for BMW B58 6-Cyl. 3.0L engines. The CHU0940 includes a high-strength aluminum connector and gasket, while the CHK0940 adds a built-in temperature sensor for easy installation. The CRP Automotive Innovation Council identified the OE plastic connector as a common failure point, often cracking due to repeated thermal cycling and hydrolysis. Hydrolysis, the process of water breaking down plastic or rubber, weakens the material over time, leading to failure. Rein’s upgraded aluminum connectors eliminate these issues, providing enhanced durability and reliability.

Positioned directly in the charge pipe's path, the stock B58TU upper cylinder head cooling hose, primarily made of plastic, is prone to damage. A dislodged charge pipe can easily take out this cooling hose, leading to severe engine damage through rapid coolant loss and overheating.

To address this vulnerability, VTT has engineered a robust solution. By replacing the OEM rubber hose with a durable 7-ply silicone variant, they offer superior resilience and longevity. Furthermore, they've upgraded the factory plastic flanges to 6061-T6 billet aluminum with black anodizing, enhancing corrosion resistance.

This upgraded hose is the ultimate solution, providing protection against dislodged charge pipes and the heat generated from spirited driving or track use.

Key Features:

Direct factory replacement for easy installation 6061-T6 billet aluminum with black anodizing for improved corrosion resistance Durable 7-ply silicone available in three colors Upgrade your BMW B58TU engine with this enhanced cooling hose from Vargas Turbo Technologies for superior performance and reliability.
