RacingLine Turbo Boost Hose Kit for Audi 8V/8Y RS3 & TTRS | VWR140011

Upgrade your Audi RS3 (8V.2 & 8Y) or Audi TTRS 8S with the RacingLine Turbo Boost Hose Kit for enhanced airflow, optimized performance, and rock-solid reliability under high-boost, high-temperature conditions.

Key Features:

• Precision Airflow Optimization: Replace restrictive factory charge pipes with a larger 70mm aluminum boost pipe and smooth-flow silicone hoses, reducing turbulence and enhancing turbo efficiency.

• Direct OEM Replacement: Easily swap out the weak, flexible rubber OEM hoses with this durable five-piece kit for an instant upgrade.

• Engineered for Extreme Performance:

  • 70mm O/D Aluminum Boost Pipe: Maintains a consistent 70mm diameter from the intercooler outlet to the throttle body, unlike the factory 63mm plastic pipe.

  • Smooth Internal Flow: Stepped internal joints ensure port-matched, laminar airflow, significantly reducing turbulence.

  • Heat & Boost Resistance: Pressure tested to withstand extreme heat and boost, maintaining optimal performance even under intense driving conditions.

  • Fluorosilicone Interior: Provides resistance against oil and fuel permeation, preventing long-term deterioration.

Five-Piece Boost Pipe Kit Includes:

1. 70mm Boost Pipe – Smooth aluminum design eliminates factory clearance dents to maintain airflow.

2. Intercooler Outlet Hose – Precision-molded for seamless fitment.

3. Intercooler Inlet Hose – Optimized to improve intake efficiency.

4. Turbo Outlet Hose – High-strength construction to prevent deformation under boost.

5. Throttle Body Hose – Maintains airflow consistency for throttle response improvements.

Built to Handle the Heat:

• Reinforced Silicone Construction: High-quality silicone prevents deformation, even under extreme heat and boost loads.

• Stainless Steel Mikalor Clamps: Deliver extra grip and prevent boost leaks.

• Convolutions & Stainless Steel Bands: Allow engine movement while preventing hose collapse.

Why Upgrade?

By reducing airflow restrictions, optimizing routing, and improving durability, the RacingLine Boost Hose Kit allows your turbo to work more efficiently. The result? More consistent performance, better throttle response, and greater reliability on both road and track.
