Forge Motorsport Diverter Valve Hose & Adaptor Kit for Audi RS3 8Y, RSQ3 F3, TTRS 8S & Cupra Formentor VZ5

When modifying the high-performance VAG 2.5 TFSI powerplant, hardware shifts between production cycles can present installation challenges. When looking to fit the Forge carbon fibre induction kit to a 2019-onwards vehicle powered by the updated DNWA engine configuration, you will discover that the factory diverter valve hose connection to the DV elbow demands a specialized engineering adaptation. While earlier production variants utilized standard round silicone joins, later global setups implement a distinct rectangular coupler profile. The Forge FMBH8 package provides the perfect fit-and-forget fix for this requirement.

Key Engineering Features

6082 Billet Joiner: Fully CNC machined in-house by Forge engineers at their UK Gloucestershire headquarters, then beautifully anodized.
Reinforced 4-Ply Silicone: Drastically enhances under-bonnet aesthetics while far exceeding the structural longevity of the cheap OEM plastic line.
Water/Methanol Integration Port: Features a built-in 1/8th NPT threaded boost take-off or methanol port supplied with a secure blanking plug.
Future-Proof Componentry: Allows flexible routing configurations when moving onward to advanced forced-induction modifications.
Fluorosilicone Barrier: Specialized lining resists chemical breakdown when in direct contact with coolants or oil-laden intake vapors.

System Integration and Specifications

Although this premium upgrade has been created directly alongside the Forge carbon induction setup, the generic geometry allows smooth cross-compatibility with several alternative aftermarket intake systems. The included plumbing hose configuration options are available in Black, Blue, or Red color finishes, keeping the unit adaptable across any custom engine bay theme without altering underlying technical dimensions.
