The Wagner Tuning 09-16 Audi A4 B8 (Allroad) 2.7TDI Silicone Hose Kit is a silicone hose replacement kit designed to replace the factory rubber intercooler couplers with heat-resistant silicone that maintains a consistent seal under elevated boost and temperature. Factory rubber couplers degrade over time and are prone to cracking or blow-off under increased boost pressure, causing boost leaks and inconsistent power delivery. This Wagner kit addresses that weak point with multi-ply reinforced silicone construction.
Direct OEM-position fitment matching factory coupling sizes and routing. Includes all clamps and hardware. A straightforward upgrade for any turbocharged build where hose integrity matters.
