Racingline R600 Silicone Coolant Re-Route Hose – EA888 Gen.4
The Racingline R600 Silicone Coolant Re-Route Hose is a purpose-built upgrade for EA888 Gen.4 engines fitted with the Racingline R600 cold-air intake system. It’s a small part that solves a real problem, tidying up the engine bay while delivering the durability needed for modern VW Group cooling systems.
Why You Need This Hose
On many MQB ‘EVO’ cars, the factory coolant hose runs directly over the top of the engine, partially covering your R600 intake and leaving the engine bay looking cluttered. This direct-replacement hose reroutes the coolant line underneath the intake, giving you a much cleaner, show-quality finish that does justice to the rest of your build.
Built for the Job
This is more than a cosmetic tweak. The hose is constructed from reinforced 4-ply silicone, designed to handle the pressures and temperatures of your engine’s cooling system without flexing or failing over time. It also features a Fluoro inner liner, making it fully compatible with the aggressive G12 and G13 coolants used in modern VW Group cars. Standard silicone hoses can degrade when exposed to these coolants, so this lining is an important detail that ensures long-term reliability.
Crucially, the hose includes a new factory one-way valve, a component the cooling system relies on for correct operation. Nothing is left to chance, and the part fits and functions exactly like the original.
- Clean aesthetics: reroutes the coolant hose beneath the R600 intake for a tidy, uncluttered look
- Premium construction: 4-ply reinforced silicone with a Fluoro inner liner for full G12/G13 coolant compatibility
- Correct function: includes a new factory one-way valve
- Direct replacement: uses original mounting points for a straightforward installation
Important Fitment Information
This hose fits EA888 Gen.4 engines equipped with the Garrett turbocharger only. It will NOT fit cars fitted with the Continental turbo (300-333PS models).
It is designed to be used alongside the Racingline R600 cold-air intake system on popular MQB ‘EVO’ platform cars including Golf R, Cupra and Audi S3 variants running the EA888.4 engine. Please use the vehicle lookup on our site or check the Vehicle Fitment tab to confirm compatibility with your car before ordering.
A small detail, done properly. If you’ve fitted the R600 intake, this is the finishing touch that ties everything together while keeping your cooling system performing as it should.
