PRODUCT DESCRIPTION
RacingLine's R600 Coolant Under Hose reroutes the unsightly factory hose underneath your intake for a much cleaner look. It incorporates the all-important non-return valve. A simple, practical upgrade for any R600 intake.
The details make the difference, and that includes the appearance of your engine bay.
RacingLine's R600 Coolant Under Hose simply positions the unsightly factory coolant hose underneath your intake to give your car and your intake the clean and tidy appearance they deserve.
As you'd expect from RacingLine, even a simple part like this hose is designed with care and attention to detail.
The hose is manufactured from 4-ply reinforced silicone rubber to withstand the high pressures of the cooling system. It features an inner fluorine lining to be compatible with the G12 and G13 coolant used in MQB vehicles, which is very aggressive on conventional silicone.
This high-quality, precision-molded, high-temperature-resistant silicone rubber material withstands coolant temperatures beyond any limits and maintains its rigidity to retain its perfect shape for the entire life of the vehicle.
Most importantly, the hose includes a factory non-return valve, just like the original pipe. Some coolant relocation hoses do not include this valve; we strongly recommend that you do not use your vehicle without it.
