RacingLine Upgraded Boost Hose Kit 2.0 TSI / 1.8 TSI EA888 Gen.3 & 3B (MQB Platform)

RacingLine Upgraded Boost Hose Kit – 2.0 TSI / 1.8 TSI EA888 Gen.3 & 3B (MQB Platform)
Part Number: VWR140004

Improve the airflow, pressure stability and reliability of your 2.0 TSI or 1.8 TSI EA888 Gen.3 / Gen.3B engine with the RacingLine Upgraded Boost Hose Kit.
This premium kit replaces the original rubber hoses with high-quality, reinforced silicone boost hoses with internal wire reinforcement – designed for maximum performance under high pressure and temperature.

What does the Boost Hose Kit do?

The standard rubber charge pipes of MQB-platform cars are susceptible to deformation and pressure loss under high load.
The RacingLine Boost Hose Kit solves this problem by creating a smooth, reinforced airflow with minimal turbulence and maximum pressure retention.

Each hose is internally reinforced and designed with step-to-step internal transitions, ensuring a port-matched, laminar flow without resistance.
The result: faster turbo spool, more stable boost, and instant throttle response – time after time, even under extreme conditions.

Key features

• 5-piece set (4 hoses needed, 1 variant depending on year of manufacture)

• Internal wire reinforcement – prevents deformation at high boost

• Stepped internals – for perfectly laminar airflow

• Fluorosilicone inner layer – resistant to oil and fuel vapors

• Hand-wound multi-layer silicone construction – extremely heat and pressure resistant

• Stainless steel Mikalor clamps – leak-free connection with maximum grip

• Direct OEM replacement – easy to install without modifications

High performance, guaranteed

• Constant boost pressure without leaks or pressure drop

• Improved turbo spool and power increase

• Resistant to high temperatures and extreme loads

• Long-term reliability with intensive use

• Perfectly combinable with the RacingLine Boost Pipe Kit (VWR140012)
