Forge Motorsport Premium Multi-Ply Fluorosilicone Boost Hose Kit for Audi RS6 & RS7 (C7 4.0 TFSI)

The high-output 4.0-litre twin-turbocharged V8 engine powering the Audi C7 RS6 and RS7 generates immense heat and high boost pressures, especially on vehicles running aftermarket performance software. Under these intense conditions, the flexible factory rubber charge lines expand, resulting in modern boost leaks, unstable pressure regulation, and a noticeable drop in acceleration. To resolve this performance bottleneck, Forge Motorsport developed this ultra-robust, multi-ply reinforced silicone boost hose replacement package.

Key Engineering Features

  • Advanced Fluorosilicone Liner: Built with a premium internal liner that prevents discoloration and protects against degradation from oil mist and Organic Acid Technology (O.A.T.) coolants.
  • Multi-Ply Fabric Reinforcement: Constructed from thick, high-tensile structural silicone layers that handle high boost levels without expanding.
  • Smooth-Bore Internal Path: Eliminates internal steps and airflow restrictions to minimize turbulence and optimize turbocharger spool response.
  • технічні Longevity: Far outlasts standard factory rubber components under extreme engine bay thermal cycling, preventing costly boost leaks.
  • Direct Plug-and-Play Fit: Molded to match original factory dimensions exactly, keeping installation clean and straightforward.

Generic Color Profiles & Custom Options

This premium performance modification replaces the flexible factory lines to ensure consistent, reliable charge flow during back-to-back runs. This product is fully available in choice configurations across vibrant Red, bold Blue, or deep Black styling choices, allowing you to customize your engine bay layout while maintaining identical technical performance metrics.

WORKSHOP PERFORMANCE TIP: For the ultimate charge-cooling combination, pair this boost hose kit directly with the matching Forge PolarCooler auxiliary front radiator upgrade.
