Forge Motorsport DV to Intake Return Hose for Audi S3, TTS, SEAT Leon, and VW Golf

Forge Motorsport Silicone Diverter Valve to Intake Return Hose for VAG 2.0 TFSI (EA113 K04 Platforms)

High-performance VAG 2.0 FSiT engines equipped with larger K04 turbochargers use a unique diverter valve configuration. Unlike standard K03 setups, these platforms position the diverter valve at the front of the engine bay, requiring a long return link to the rear air intake. This critical path is subjected to intense engine movement and heat cycling, causing standard factory rubber hoses to soften and fail. The Forge FMRLH high-performance silicone hose replaces this weak link, ensuring dependable airflow and reliable long-term boost management.

Key Engineering Features

• Optimized Internal Geometry: Smooth inner bore ensures maximum airflow and highly responsive boost relief.
• Premium Fluorosilicone Liner: Prevents deterioration from oil mist and modern long-life Organic Acid Technology (O.A.T.) coolants.
• Exceeds Factory Specifications: Multi-ply reinforced construction withstands high engine bay temperatures without collapsing under vacuum.
• Enhanced Engine Bay Styling: Replaces ugly, degraded factory rubber pipes with a premium, long-lasting look.
• MGM Workshop Favorite: An essential fit-and-forget upgrade for tuned or remapped K04 VAG vehicles, backed by a lifetime warranty.
