Silicone Intake Coolant Underhose for VW Golf MK7 R GTI S3 TTS

Engineered specifically for MQB platform vehicles, this silicone intake coolant underhose restores optimal cooling system efficiency while handling increased thermal loads without expanding or degrading. The hose features a precision-moulded design that retains its exact geometry over time, paired with a reinforced 4-ply construction capable of enduring the elevated pressures typical of modern turbocharged engines.

A critical factory-design one-way valve is permanently integrated into the unit, ensuring fluid circulates in the correct direction exactly as intended by the manufacturer. An inner fluoro lining provides full chemical compatibility with G12 and G13 coolants commonly used across Volkswagen Group platforms, while the premium temperature-resistant silicone prevents cracking or leakage during extreme heat cycles.

Benefits & Tips

• Pair this upgrade with a complete cooling system flush to eliminate old sediment and maximize fresh coolant flow through the new route path.
• Always install hose clamps according to your vehicle service manual torque specs to prevent micro-leaks under sustained high-RPM operation.
• Ideal for daily performance driving, autocross, or track weekends where stock rubber hoses tend to soften and restrict circulation.
