Racingline R600 Coolant Hose

RacingLine R600 Coolant Underhose – 2.0 TSI MQB / MQB Evo

The RacingLine R600 Coolant Underhose VWR17 G7R600 is a high-quality silicone coolant hose designed for vehicles fitted with the RacingLine R600 intake system.

The factory coolant hose often runs over the intake system, visually detracting from the otherwise clean appearance of the engine bay. RacingLine solves this problem by rerouting the hose underneath the R600 intake, achieving a much tidier and more complete OEM+ look.

This is a small but very significant detail for any vehicle with an R600 intake system. Instead of the factory hose being visibly positioned over the beautiful intake housing, the RacingLine Underhose discreetly moves it underneath, making the engine bay appear cleaner, more premium, and more complete.

Importantly, RacingLine didn't just make a simple silicone hose. It integrates a factory one-way valve, just like the original hose. This valve is critical for the proper operation of the system, so the vehicle should not be driven without it.

The hose is made from 4-layer reinforced silicone, designed to withstand the pressure and temperature in the cooling system. The internal fluoro layer is compatible with G12 and G13 coolant used in MQB vehicles, and the precisely molded construction maintains the correct shape throughout the vehicle's lifespan.

Why does this upgrade matter?

When you've already invested in a RacingLine R600 intake system, the visible factory hose above it can detract from the overall look of the engine bay. The RacingLine R600 Coolant Underhose solves this detail by moving the hose underneath the intake, leaving the top clean and tidy.

Beyond the visual benefit, the construction is done correctly — with a preserved one-way valve, reinforced silicone structure, and compatibility with factory coolant.
