URO 11-53-7-578-687 Turbocharger Coolant Feed Line for Cylinders 1-4

The URO 11-53-7-578-687 is a turbocharger coolant feed line designed to supply coolant to the turbocharger serving cylinders 1-4. This essential cooling system component helps maintain optimal turbocharger operating temperatures by circulating coolant through the turbo housing, preventing overheating and extending turbocharger life.

Key Features:

• Engineered specifically for cylinders 1-4 turbocharger cooling circuit
• Includes metal hose fitting for secure, leak-resistant connection
• Features improved heat shield design for enhanced thermal protection
• Precision-manufactured to OEM specifications for proper fit and function
• Replaces BMW OEM part number 11-53-7-578-687

This turbocharger coolant line is a direct replacement for worn or damaged original equipment. The integrated metal fitting ensures reliable sealing under high temperature and pressure conditions, while the upgraded heat shield provides superior protection against radiant heat from nearby engine components. Proper coolant flow through this line is critical for turbocharger longevity and preventing catastrophic turbo failure due to inadequate cooling.
