Description
Optimize your turbocharged VAG engine’s performance and reliability with the Forge Motorsport Diverter Valve (DV) to Intake Return Hose, specifically designed for 2.0L FSiT-equipped vehicles such as the Audi S3, TTS, SEAT Leon Cupra, and VW Golf GTI and R models.
This premium silicone hose provides a direct replacement for the factory rubber hose that runs between the diverter valve at the front of the engine and the air intake at the rear. Over time, OEM hoses can degrade due to high heat, oil vapor exposure, and pressure fluctuations—making this reinforced, high-performance upgrade a must-have for long-term durability and consistent boost response.
Crafted from multi-ply, European-grade silicone and lined with a Fluorosilicone inner layer, this hose offers superior resistance to chemical breakdown, making it suitable for applications involving oil mist, O.A.T. coolants, and modern long-life antifreezes. Designed to exceed OEM standards, this hose not only improves reliability but also adds a visual performance touch to your engine bay.
Available in Red, Blue, or Black, this is a functional and aesthetic upgrade backed by the Forge Motorsport Lifetime Warranty.
